MatchMeshEdge C# Component

Hi Everyone,

I'm looking for some help getting a very simple C# component to work. My goal is to execute the MatchMeshEdge command from within Grasshopper. Since this command is not exposed in the RhinoCommonSDK, I modified a working C# component that does something similar (ReduceMesh, written by Andrew Heumann). Both scripts are attached.

Aside from changing the component name and eliminating the P parameter, I made two modifications to the script:
1) changed line 87 from
   private void RunScript(Mesh M, double P, ref object A)
   to:
   private void RunScript(Mesh M, ref object A)

2) changed line 93 from:
   Rhino.RhinoApp.RunScript("_-ReduceMesh _ReductionPercentage " + Convert.ToString(P) + " _Enter", false);
   to:
   Rhino.RhinoApp.RunScript("_-MatchMeshEdge " + " _Enter", false);

When I run the ReduceMesh component, the mesh object I feed it gets baked, the ReduceMesh command is run, the temporary object is deleted, and the reduced mesh result is returned. (Thanks, Andrew).

When I run the MatchMeshEdge component, the mesh object I feed it is baked, the MatchMeshEdge command is run, but the temporary object is not deleted and no result is returned. The runtime error reads: "Sequence contains no elements (line 0)".

I have a feeling that the command line string I am handing to RunScript is incomplete. When I enter it manually on the Rhino command line I see that it wants a mesh and three parameters. Of course I can hit Enter to accept the default values, but when you invoke a command through RunScript do you have to supply all parameters regardless? Also, where would I find details on the argument types that the command wants? For example, the last parameter reads "RatchetMode=On" or "RatchetMode=Off". How do I know if the type is Bool or the literal string "On" or "Off"?

I am a complete novice at this so any help you can provide would be greatly appreciated!
