FXCOP-空的catch块捕获规则

我已经写了醒目空的catch块，使用fxcop.But扔。我声明要编写一个规则，它抛出一个警告消息，空的catch块捕获块。规则
任何帮助将apprecited。

public override ProblemCollection Check(Member member)

        {

            Method method = member as Method;

            bool isCatchExists = false;

           bool isThrowExists = false;

            Instruction objInstr = null;

            if (method != null)

            {

                InstructionList iList = method.Instructions;

 

                for (int i = 0; i < iList.Length; i++)

                {

                    if (iList[i].OpCode == OpCode._Catch)

                    {

                        isCatchExists = true;

                    }

 

                    if (isCatchExists)

                    {

                       

                    }

 



                    if (isCatchExists)

                    {

                        //If the call is not made to HandleError method. 

                        if (!isThrowExists)

                        {

                            Resolution resolu = GetResolution(new string[] { method.ToString() });

                            Problems.Add(new Problem(resolu));

                        }

                    }

 

                   

                }

            }

            return Problems;

 

        }

    }
