Example

[Visual Basic, C#, C++] The following code example demonstrates how to use a TimeSpan value with the Join method.

[Visual Basic, C#, C++] Note   This example shows how to use one of the overloaded versions of Join. For other examples that might be available, see the individual overload topics.
