Thread Safety

Any public static (Shared in Visual Basic) members of this type are thread safe. Any instance members are not guaranteed to be thread safe.

Remarks

This class adds support for properties on an object to the methods and properties provided by TypeConverter. To make a type of property expandable in the PropertyGrid, specify this TypeConverter for standard implementations of GetPropertiesSupported and GetProperties.

Note   You should never access a type converter directly. Instead, call the appropriate converter by using TypeDescriptor. For more information, see the examples in the TypeConverter base class.

For more information about type converters, see the TypeConverter base class and Implementing a Type Converter.

Example

[Visual Basic, C#, C++] The following example converts a variable of type Margins to a string variable.

[Visual Basic] 
Dim strM As String
strM = "1,2,3,4"
Dim m = New System.Drawing.Printing.Margins(1, 2, 3, 4)
Console.WriteLine(TypeDescriptor.GetConverter(strM).CanConvertTo(GetType(System.Drawing.Printing.Margins)))
Console.WriteLine(TypeDescriptor.GetConverter(m).ConvertToString(m))

[C#] 
string strM="1,2,3,4";
System.Drawing.Printing.Margins  m= new System.Drawing.Printing.Margins(1,2,3,4);
Console.WriteLine(TypeDescriptor.GetConverter(strM).CanConvertTo(typeof(System.Drawing.Printing.Margins))); 
Console.WriteLine(TypeDescriptor.GetConverter(m).ConvertToString(m)); 

[C++] 
String* strM = S"1,2,3,4";
System::Drawing::Printing::Margins* m = new System::Drawing::Printing::Margins(1,2,3,4);
Console::WriteLine(TypeDescriptor::GetConverter(strM)->CanConvertTo(__typeof(System::Drawing::Printing::Margins)));
Console::WriteLine(TypeDescriptor::GetConverter(m)->ConvertToString(m));
