Boolean.ToString Method

Converts the value of this instance to its equivalent string representation (either "True" or "False").

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

public override string ToString()

Return Value

Type: System.String
TrueString if the value of this instance is true, or FalseString if the value of this instance is false.

This method returns the constants "True" or "False". Note that XML is case-sensitive, and that the XML specification recognizes "true" and "false" as the valid set of Boolean values. If the String object returned by the ToString() method is to be written to an XML file, its String.ToLower method should be called first to convert it to lowercase.

The following example illustrates the ToString method.

bool raining = false;
bool busLate = true;

Console.WriteLine("raining.ToString() returns {0}", raining);
Console.WriteLine("busLate.ToString() returns {0}", busLate);
// The example displays the following output: 
//       raining.ToString() returns False 
//       busLate.ToString() returns True
