[mapguide-users] Remove layer C#

[Campbell, Keith A]

If this is a true reproduction of your code, then you can't pass a
string to the Remove method, it needs to be a MapLayer object. You can
pass a string (or MapLayer object) to the remove method.

Subject: [mapguide-users] Remove layer C#


I'm to see if a layer exists and remove it if it exists. The layer would
have been saved as a temporary resource. Here is the code.  

// get the map
MgMap map = new MgMap(siteConnection);
map.Open(mgMapName);
	
MgLayerCollection layerCol = map.GetLayers();
	
if(layerCol.Contains("myLayer"))
{
     layerCol.Remove("myLayer");
}
	
.... Add myLayer code here .....

I get the following error whether or not the layer exists:

 Compiler Error Message: CS1502: The best overloaded method match for
'OSGeo.MapGuide.MgLayerCollection.Remove(OSGeo.MapGuide.MgLayerBase)'
has some invalid arguments

Source Error:

Line 42: 	if(layerCol.Contains("myLayer"))
Line 43: 	{
Line 44: 		layerCol.Remove("myLayer");
Line 45: 	}
Line 46: 	

Anyone have any suggestions?

Thanks in advance.
