So I created an ArcGIS 10 toolbox in ArcSDE and added a tool to it. There are enough examples out there on how to execute a tool.tbx that resides outside SDE or GeoDB. But in C#, how do you use gp.execute on a tool that resides within ArcSDE? thanks!

Try using the IToolboxWorkspace interface. Code below works for a file gdb workspace, I'd imagine it would work for arcsde too.

private static void ListToolboxes(IWorkspace ws)
    var tbxWkspc = ws as ESRI.ArcGIS.Geoprocessing.IToolboxWorkspace;
    if (tbxWkspc == null)
        Console.WriteLine("not a toolbox workspace");
    var toolboxes  = tbxWkspc.Toolboxes;
    IGPToolbox tbx;
    while ((tbx = toolboxes.Next()) != null)
        var tools = tbx.Tools;
        IGPTool tool;
        while ((tool = tools.Next()) != null)
            // you could execute here ...
            Console.WriteLine("{0}: {1}", tbx.PathName, tool.Name);

Works like a charm! I was able to find my toolbox & tool in ArcSDE. Kirk, another question. Instead of enumating thru the tools and finding a hard-coded tool name to execute, could you have the name of the tool in something like a config.xml which you could read? I will probably need to fire different tools so I am looking for flexibility. Or how would you handle this? Thanks! – saim May 8 '11 at 4:57
Sure, you'd need the name of the toolbox and the name of the tool. Open the toolbox with IToolboxWorkspace.OpenToolBox and then open the tool with IToolBox.OpenTool. – Kirk Kuykendall May 8 '11 at 14:11
I ended up using Geoprocessor gp because it was easier. I could not figure out the parameters of IGPTool.execute, because the developer help is vague with no examples. Also, I am running my custom ArcSDE model tool from a console app... Sorry, I must not have been clear. I was wondering if I could save the name of my tool and its parameters to an external xml file so I would never have to update my c# code when a new custom tool is created. thanks! – saim May 9 '11 at 4:12
