Calling method from another class from another file C#
提问by Tudor Gafiuc
I have declared a namespace in Feed.aspx.cs . This namespace contains a class and this class contains a method: Feed.aspx.cs
我在 Feed.aspx.cs 中声明了一个命名空间。这个命名空间包含一个类，这个类包含一个方法： Feed.aspx.cs
namespace GetUser
{
public class MyFeedClass
{
public string getUserID()
{
MembershipUser user = Membership.GetUser(HttpContext.Current.User.Identity.Name);
HttpContext.Current.Session["x"] = user.ProviderUserKey.ToString();
string test = (string)HttpContext.Current.Session["x"];
return test;
}
}
}
}
Now, from MyPage.aspx.cs, I'd like to call the getUserID() method. How can I do that?
现在，从MyPage.aspx.cs，我想调用 getUserID() 方法。我怎样才能做到这一点？

I guess you are using Asp.NET?
我猜你在使用 Asp.NET？
You should create a new class inside your add_code folder. Move that namespace and the class inside the new created class
您应该在 add_code 文件夹中创建一个新类。将该命名空间和类移动到新创建的类中
Then call it from your Feed.aspx.cs:
然后从您的 Feed.aspx.cs 调用它：
GetUser.MyFeedClass myfeed = new GetUser.MyFeedClass();
string result = myfeed.getUserID();

Make sure you include the namespace in your code-behind:
确保在代码隐藏中包含命名空间：
using GetUser;
Make the public function a static one in the MyFeedClass:
使公共函数成为 MyFeedClass 中的静态函数：
public static string getUserID() {...}
Then in your aspx.cs page you can now try to do:
然后在您的 aspx.cs 页面中，您现在可以尝试执行以下操作：
string userId = MyFeedClass.getUserID();
