更正参数计数不匹配

如何更正此错误我有

用户代码未处理TargetParameterCountException。参数计数不匹配。

这是发生的地方的我的代码

public static void InvokeMethod(string className, string methodName, string fileName)
{
    var t = Type.GetType(className);
    using (StreamReader f = new StreamReader("params.txt"))
    {
        t.GetMethod(methodName).Invoke(t.GetConstructor(Type.EmptyTypes).Invoke(new object[] { }), new object[] { f.ReadLine() });
    }
}

这是整个代码
