public int FindParamer(string strParamer)
        {
            CSharpCodeProvider provider = new CSharpCodeProvider();
            CompilerParameters parameter = new CompilerParameters();
            parameter.ReferencedAssemblies.Add("System.dll");
            parameter.GenerateExecutable = false;
            parameter.GenerateInMemory = true;
            CompilerResults result =
                provider.CompileAssemblyFromSource
                (
                    parameter,
                    "using System;" +
                    "namespace calculate" +
                    "{" +
                        "public static class calculation" +
                        "{" +
                        "public static int calculateExpression()" +
                        "{" +
                            "return " + strParamer +
                        ";}}}"
                );
            return Convert.ToInt32(result.CompiledAssembly.GetType("calculate.calculation").GetMethod("calculateExpression").Invoke(null,new object[]{}));
        }

上次找过一个，现在懒得找了    试试google eval + .net吧另外，可以用dynamic，查查.net的脚本语言吧
