This converter can only convert a Boolean object to and from a string.

For more information about type converters, see the TypeConverter base class and How to: Implement a Type Converter.

System_CAPS_noteNote

You should never create an instance of a BooleanConverter. Instead, call the GetConverter method of the TypeDescriptor class. For more information, see the examples in the TypeConverter base class.

The following code example converts a variable of type Boolean to and from a string.

bool bVal=true;
string strA="false";
Console.WriteLine(TypeDescriptor.GetConverter(bVal).ConvertTo(bVal, typeof(string))); 
Console.WriteLine(TypeDescriptor.GetConverter(bVal).ConvertFrom(strA));
