There are many overloaded forms of this method and among those overloaded forms, we have two forms to convert a string representation of a number to its equivalent double-precision floating-point number.Both these methods return a double value after converting the string value to double.The syntax of Convert.ToDouble() method in both its overloaded forms for converting a string to double is as follows:In the above syntax, ToDouble() method takes one argument of type string (In the above syntax, ToDouble() method takes two arguments; the first is the string representation of a number which needs to be converted to double and second is an object which provides culture-specific formatting information. double.Parse("52.8725945", System.Globalization.CultureInfo.InvariantCulture); You should also take a look at double.TryParse, you can use it with many options and it is especially useful to check wheter or not your string is a valid double. along with different examples and its code implementation. THE CERTIFICATION NAMES ARE THE TRADEMARKS OF THEIR RESPECTIVE OWNERS.This website or its third-party tools use cookies, which are necessary to its functioning and required to achieve the purposes illustrated in the cookie policy. Among these overloaded forms, two forms allow us to convert a string representation of a number to its equivalent double-precision floating-point number.Let us understand the working of the above method with the help of the below example:In the above statement, we have passed a number i.e. Parses the C string str, interpreting its content as a floating point number and returns its value as a double. Then, starting from this character, takes as many characters as possible that are valid following a … Example.

In the same way, we can convert a string to double using a method present inside the “Convert” class called ToDouble() method. An object of each class is passed to the ToDouble method. The function first discards as many whitespace characters (as in isspace) as necessary until the first non-whitespace character is found. Converts a specified value to a double-precision floating-point number.Converts the value of the specified 8-bit signed integer to the equivalent double-precision floating-point number.Converts the value of the specified object to an double-precision floating-point number, using the specified culture-specific formatting information.Converts the value of the specified 64-bit unsigned integer to an equivalent double-precision floating-point number.Converts the value of the specified 32-bit unsigned integer to an equivalent double-precision floating-point number.Converts the value of the specified 16-bit unsigned integer to the equivalent double-precision floating-point number.Converts the specified string representation of a number to an equivalent double-precision floating-point number.Converts the value of the specified single-precision floating-point number to an equivalent double-precision floating-point number.Converts the specified string representation of a number to an equivalent double-precision floating-point number, using the specified culture-specific formatting information.Converts the value of the specified object to a double-precision floating-point number.Converts the value of the specified 32-bit signed integer to an equivalent double-precision floating-point number.Converts the specified Boolean value to the equivalent double-precision floating-point number.Converts the value of the specified 8-bit unsigned integer to the equivalent double-precision floating-point number.Converts the value of the specified 64-bit signed integer to an equivalent double-precision floating-point number.Converts the value of the specified decimal number to an equivalent double-precision floating-point number.Returns the specified double-precision floating-point number; no actual conversion is performed.Converts the value of the specified 16-bit signed integer to an equivalent double-precision floating-point number.Converts the value of the specified 8-bit signed integer to the equivalent double-precision floating-point number.The following example converts each element in an array of Converts the value of the specified object to an double-precision floating-point number, using the specified culture-specific formatting information.An object that supplies culture-specific formatting information.A double-precision floating-point number that is equivalent to The following example defines a class that implements Converts the value of the specified 64-bit unsigned integer to an equivalent double-precision floating-point number.A double-precision floating-point number that is equivalent to The following example converts each element in an array of Converts the value of the specified 32-bit unsigned integer to an equivalent double-precision floating-point number.A double-precision floating-point number that is equivalent to The following example converts each element in an array of Converts the value of the specified 16-bit unsigned integer to the equivalent double-precision floating-point number.A double-precision floating-point number that is equivalent to The following example converts each element in an array of Converts the specified string representation of a number to an equivalent double-precision floating-point number.A double-precision floating-point number that is equivalent to the number in The following example attempts to convert each element in an array of numeric strings to a If you prefer not to handle an exception if the conversion fails, you can call the Converts the value of the specified single-precision floating-point number to an equivalent double-precision floating-point number.A double-precision floating-point number that is equivalent to Converts the specified string representation of a number to an equivalent double-precision floating-point number, using the specified culture-specific formatting information.An object that supplies culture-specific formatting information.A double-precision floating-point number that is equivalent to the number in The following example converts string representations of If you prefer not to handle an exception if the conversion fails, you can call the Converts the value of the specified object to a double-precision floating-point number.A double-precision floating-point number that is equivalent to The following example attempts to convert each value in an object array to a Converts the value of the specified 32-bit signed integer to an equivalent double-precision floating-point number.A double-precision floating-point number that is equivalent to Converts the specified Boolean value to the equivalent double-precision floating-point number.Converts the value of the specified 8-bit unsigned integer to the equivalent double-precision floating-point number.The double-precision floating-point number that is equivalent to This conversion is not supported.
Examples. Here we also discuss the Introduction and how to convert string to double in c#? 2) You have an incorrect double.

Then, we set some important properties for this object like NumberDecimalSeparator and NumberGroupSeparator.Example showing the conversion of string to double using Convert.ToDouble() method.Example showing the conversion from string to double using Double.TryParse() method.Example showing scenario when the string to be converted to double is either ‘null’ or empty.This is a guide to Convert String to Double in C#. No value is returned. You may also have a look at the following articles to learn more –© 2020 - EDUCBA. The following example defines a class that implements IConvertible and a class that implements IFormatProvider.Objects of the class that implements IConvertible hold an array of Double values. After conversion both these methods return the equivalent double value for the string passed as the argument.In C#, the “System” namespace contains a class called “Convert” which contains the ToDouble() method in many overloaded forms to convert the specified type of data to its equivalent double value. This method returns an average of the array of Double values, using the object that implements IFormatProvider to …
