1、来定义一个接口
public interface ICustom
{
string Get();
}
2、创建接口的两个实现CustomA和CustomB
CustomA
public class CustomA : ICustom
{
public string SendTimeout { get; set; }
public string Address { get; set; }
public CustomA(string sendTimeout, string address)
{
this.SendTimeout = sendTimeout;
this.Address = address;
}
public string Get()
{
return string.Concat("CustomA ",SendTimeout," ", Address);
}
}
CustomB
public class CustomB : ICustom
{
public string SendTimeout { get; set; }
public string Address { get; set; }
public CustomB(string sendTimeout, string address)
{
this.SendTimeout = sendTimeout;
this.Address = address;
}
public string Get()
{
return string.Concat("CustomB ", SendTimeout, " ", Address);
}
}
注意:实现中需要实现一个带两个参数的构造函数,我们会在动态调用中传入这两个参数
3、 应用Activator.CreateInstance动态调用指定的ICustom的实现
Code
ICustom iCustom = null;
Type type = Type.GetType("CSDN.Profile.Statistic.WebTest.CustomA,CSDN.Profile.Statistic.WebTest");
if (type != null)
{
iCustom = (ICustom)Activator.CreateInstance(type, new object[] { "00:00:03", "net.pipe://localhost/StatisticProvider" });
}
string str = iCustom.Get();
Response.Output.Write(str);
返回的结果是CustomA 00:00:03 net.pipe://localhost/StatisticProvider
显示已经成功通过配置type来动态构建了一个相对应的接口了。
