Convert.ToString Method (Double)

Converts the value of the specified double-precision floating point number to its equivalent String representation.

Namespace: System
Assembly: mscorlib (in mscorlib.dll)

public static string ToString (
	double value
)
public static String ToString (
	double value
)
public static function ToString (
	value : double
) : String
Not applicable.

Parameters

value

A double-precision floating point number.

Return Value

The String equivalent of the value of value.

This implementation is identical to Double.ToString.

The following code sample illustrates the conversion of a Double to a String, using ToString.

public void ConvertDoubleString(double doubleVal) {
    
    string    stringVal;     

    // A conversion from Double to string cannot overflow.       
    stringVal = System.Convert.ToString(doubleVal);
    System.Console.WriteLine("{0} as a string is: {1}",
        doubleVal, stringVal);

    try {
        doubleVal = System.Convert.ToDouble(stringVal);
        System.Console.WriteLine("{0} as a double is: {1}",
            stringVal, doubleVal);
    } 
    catch (System.OverflowException) {
        System.Console.WriteLine(
            "Conversion from string-to-double overflowed.");
    }
    catch (System.FormatException) {
        System.Console.WriteLine(
            "The string was not formatted as a double.");
    }
    catch (System.ArgumentException) {
        System.Console.WriteLine(
            "The string pointed to null.");
    }
}

public void ConvertDoubleString(double doubleVal)
{
    String stringVal;

    // A conversion from Double to string cannot overflow.       
    stringVal = System.Convert.ToString(doubleVal);
    System.Console.WriteLine("{0} as a string is: {1}", 
        System.Convert.ToString(doubleVal), stringVal);
    try {        
        doubleVal = System.Convert.ToDouble(stringVal);
        System.Console.WriteLine("{0} as a double is: {1}", stringVal, 
            System.Convert.ToString(doubleVal));
    }
    catch (System.OverflowException exp) {        
        System.Console.WriteLine(
            "Conversion from string-to-double overflowed.");
    }
    catch (System.FormatException exp) {        
        System.Console.WriteLine(
            "The string was not formatted as a double.");
    }
    catch (System.ArgumentException exp) {        
        System.Console.WriteLine("The string pointed to null.");
    }
} //ConvertDoubleString
