You can specify the entry-point name by supplying a string indicating the name of the DLL containing the entry point, or you can identify the entry point by its ordinal. Ordinals are prefixed with the # sign, for example, #1. If you omit this field, the common language runtime uses the name of the.NET method marked with the System.Runtime.InteropServices.DllImportAttribute.
For additional information, see [<topic://cpconidentifyingfunctionsindlls>]. For examples showing how to use the DllImportAttribute.EntryPoint field, see Specifying an Entry Point.
