System.InvalidCastExcecption while trying to call a C# routine which accepts String arrays as parameters

the way to tackle this is to make everything an object in the c# code.



public   static Object [] checkArray(Object [] a1, Object []  a2)

{

    var results = a1.Except(a2);

    Object[] result = results.ToArray();

    return result;

}



and in your TestComplete code use, this function provided by smart bear to convert your JScript array into a variant array,.

function ConvertJScriptArray(JScriptArray)

{

  // Uses the Dictionary object to convert a JScript array

  var objDict = Sys.OleObject("Scripting.Dictionary");

  objDict.RemoveAll();

  for (var i in JScriptArray)

    objDict.Add(i, JScriptArray);

  return objDict.Items();

}







/my sample jscript code:

var strarray = new Array();

strarray[0]= "1";

var strarray1 = new Array();

strarray1[0]= "1";

//checkArray is the C# method

dotNET.ClassLibrary1.Program1.checkArray(ConvertJScriptArray(strarray),ConvertJScriptArray(strarray1));
