问题描述

亲爱的朋友们

这是我的代码

Dear Friends

I have a error in my wcf application. The name of error is Exception has been thrown ny the target of invocation.

Here is my code

public string GetData(int value)
      {
        string  XMLStr;
        string  VchSeries ;
      string  VchDate ;
      Int32 VchType;
      string VchNo;
      Int32 AutoVchNo;
      string Narration ;
      double Amt;
      string ErrMsg ;
      object CFixedInterface = new object();
       object[] objArgs ;
          object[]  objArgs1;
           objArgs =new object[10];
           objArgs1 = new object[10];

      ErrMsg = "";

      Type  ObjectType = Type.GetTypeFromProgID("Busy1214h.CFixedInterface");
      CFixedInterface = Activator.CreateInstance(ObjectType);

      objArgs[4] = new object();
      objArgs[0] = @"C:\Busywin\";
      objArgs[1] = "comp4";
      objArgs[2] = "sa";
      objArgs[3] = "1234";
      objArgs[4] = "BusyComp0031";
      //FI.opencsdb("C:\Busywin\", "Rachna", "sa", "busy", "BusyComp0010")

The error will come under this method:

      ObjectType.InvokeMember("opencsdb", BindingFlags.InvokeMethod, null, CFixedInterface, objArgs);
