二.ashx代码：
public class Handler1 : IHttpHandler, IRequiresSessionState
{
HttpRequest Request;
HttpResponse Response;
public void ProcessRequest(HttpContext context)
{
Request = context.Request;
Response = context.Response;
string method = Request["Method"].ToString();//对应ajax方法的url参数
MethodInfo methodInfo = this.GetType().GetMethod(method);//
methodInfo.Invoke(this, null);
}
public void getLzr() {
string name = Request["name"].ToString();
string age = Request["age"].ToString();
string sex = Request["sex"].ToString();
int i = SqlHelper.ExecuteNonQuery("Insert into lzr_name(name,age,sex) values(@name,@age,@sex)", new SqlParameter("@name",name), new SqlParameter("@age", age), new SqlParameter("@sex", sex));
if (i > 0)
{
//返回的数据
Response.Write("T");
}
else
{
Response.Write("F");
}
}
public bool IsReusable
{
get
{
return false;
}
}
}
