Converts the value of the specified 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. Calling this method always throws InvalidCastException. Converts the value of the specified 8-bit unsigned integer to the equivalent double-precision floating-point number.

An object that implements the IConvertible interface. A double-precision floating-point number that is equivalent to value , or zero if value is null. 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. An object of each class is passed to the ToDouble method. This method returns an average of the array of Double values, using the object that implements IFormatProvider to determine how to calculate the average.

The return value is the result of invoking the IConvertible. ToDouble method of the underlying type of value. For example, if value is a String that represents a number, provider could supply culture-specific information about the notation used to represent that number. The base types ignore provider ; however, the parameter may be used if value is a user-defined type that implements the IConvertible interface.

A double-precision floating-point number that is equivalent to value. The following example converts each element in an array of UInt64 values to a Double value. The following example converts each element in an array of UInt32 values to a Double value. The following example converts each element in an array of UInt16 values to a Double value. A double-precision floating-point number that is equivalent to the number in value , or 0 zero if value is null.

The following example attempts to convert each element in an array of numeric strings to a Double. The example's output is from a system whose current culture is en-US. Using the ToDouble String method is equivalent to passing value to the Double. Collectives on Stack Overflow. Learn more. How can I convert textbox value to double in c? Ask Question.
