Type t = typeof(TestA);

string str = (string)mt.Invoke(ta, new object[] { 5 });

//方法2
//加載程序集
Assembly s = Assembly.Load("zhiXing");
//獲得類
Type tpe = s.GetType("zhiXing.TestA");
//獲得方法
MethodInfo method = tpe.GetMethod("My");
//安全判斷
{
//獲取須要傳入的參數
ParameterInfo[] parms = method.GetParameters();
//這裏是判斷參數類型
foreach (ParameterInfo ss in parms)
{
if (ss.ParameterType == typeof(int))
{
Console.WriteLine("參數類型匹配");
}
else
{
Console.WriteLine("參數類型不匹配");
}

}
//獲取 類的對象
object obj = s.CreateInstance("zhiXing.TestA");
//調用
method.Invoke(obj, new object[] { 5 });

public class TestA

public void My(int a)
