int CDotNetInvokeMember (CDotNetAssemblyHandle assembly, const char *typeName, CDotNetHandle instance, int invokeMechanism, const char *memberName, size_t numberOfParameters, unsigned int parameterTypes[], void * parameters[], unsigned int returnType, void *returnValue, CDotNetHandle *exception);

Purpose

Calls the specified member of the specified .NET object. You can use this function to call methods, get and set properties, and get and set fields.

The signature of the called member must match the arguments you pass to the parameters of this function.

Parameters

Input
Name	Type	Description
assembly	CDotNetAssemblyHandle	The handle of the .NET assembly that defines the .NET type whose member you want to call. Note  If you pass an invalid handle, the .NET execution engine can get corrupted. This can result in an execution engine exception that the library cannot handle, which will cause the system to terminate your program.
typeName	const char *	The name of the .NET type whose member you want to call.
instance	CDotNetHandle	The handle of the .NET object whose member you want to call. Note  If you pass an invalid handle, the .NET execution engine can get corrupted. This can result in an execution engine exception that the library cannot handle, which will cause the system to terminate your program.
invokeMechanism	int	The mechanism to use to invoke the member. You must use one of the following mechanisms: CDOTNET_CALL_METHOD CDOTNET_GET_PROPERTY CDOTNET_SET_PROPERTY CDOTNET_GET_FIELD CDOTNET_SET_FIELD
memberName	const char *	The name of the member to call.
numberOfParameters	size_t	The number of parameters to pass to .NET.
parameterTypes	unsigned int []	An array containing the types of the parameters to pass to .NET.
parameters	void * []	An array containing the parameters to pass to .NET. Note  All the parameters must be passed by reference.
returnType	unsigned int	The type of the return value of the call to the member. Pass zero if there is no return value.
Output
Name	Type	Description
returnValue	void *	The return value of the call to the member. You can pass NULL for this parameter.
exception	CDotNetHandle	The handle to an exception thrown by .NET. If .NET throws an exception, you can pass this handle to CDotNetGetExceptionInfo to get information from the exception object. You can pass NULL for this parameter.
