Methods

Dispose()

Clean up resources

Declaration
public void Dispose()

Invoke(Action<T>)

Code to executed with current COM-object. Code will be executed in sub thread with MTA apartment state - this will work for all COM-objects, but it should be created also from thread with MTA apartment state

Declaration
public void Invoke(Action<T> action)
Parameters
Type Name Description
Action<T> action

Invoke(Func<T, TResultStatus>)

Code to executed with current COM-object. Code will be executed in sub thread with MTA apartment state - this will work for all COM-objects, but it should be created also from thread with MTA apartment state

Declaration
public void Invoke(Func<T, TResultStatus> actionWithStatus)
Parameters
Type Name Description
Func<T, TResultStatus> actionWithStatus

InvokeAndWrap<TResult>(Func<T, (TResult, TResultStatus)>)

Code to executed with current COM-object. Code will be executed in sub thread with MTA apartment state - this will work for all COM-objects, but it should be created also from thread with MTA apartment state.
