DllImportAttribute.CallingConvention Field

Indicates the calling convention of an entry point.

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

public CallingConvention CallingConvention

You set this field to one of the CallingConvention enumeration members. The default value for the CallingConvention field is Winapi, which in turn defaults to StdCall convention.

For more information, see Calling Convention in the MSDN library.

In some cases, Visual Basic developers use the DllImportAttribute, instead of the Declare statement, to define a DLL function in managed code. Setting the CallingConvention field is one of those cases.
