Platform Invoke Examples

The following examples demonstrate how to define and call the MessageBox function in User32.dll, passing a simple string as an argument. In the examples, the xref:System.Runtime.InteropServices.DllImportAttribute.CharSet?displayProperty=nameWithType field is set to Auto to let the target platform determine the character width and string marshalling.
