C#动态创建类实例并调用

类定义：

namespace DynamicFuncTest
{
    class BaseTestClass
    {
        public virtual string TestFunction01()
        {
            return "BaseTestClass TestFunction01";
        }

        public virtual string TestFunction02(string sText)
        {
            return "BaseTestClass TestFunction02" + sText;
        }
    }

    class TestClass01 : BaseTestClass
    {
        public override string TestFunction01()
        {
            return "TestClass01 TestFunction01";
        }

        public override string TestFunction02(string sText)
        {
            return "TestClass01 TestFunction02" + sText;
        }
    }

    class TestClass02 : BaseTestClass
    {
        public override string TestFunction01()
        {
            return "TestClass02 TestFunction01";
        }

        public override string TestFunction02(string sText)
        {
            return "TestClass02 TestFunction02" + sText;
        }
    }

动态创建并调用：

        private void Btn_Execute_Class_Click(object sender, EventArgs e)
        {
            if (T_Function_Class.Text.Length == 0)
            {
                MessageBox.Show("Pls choice class.");
                return;
            }

            string sClassName = string.Format("DynamicFuncTest.{0}", T_Function_Class.Text);
            BaseTestClass test = (BaseTestClass)Activator.CreateInstance(System.Type.GetType(sClassName));

            //T_Result_Class.Text = test.TestFunction01();
            T_Result_Class.Text = test.TestFunction02(T_Params_Class.Text);
        }

其中T_Function_Class.Text为选中的类名
