在ASP.NET C＃中删除具有UserId的用户

Question

I have a dropdownlist that contains values for all the UserId in the system. When I click a button I want to delete the selected user by using their UserId. Do I need to convert the UserId into a username before I can delete it? Here is my code that I have so far:

protected void btnDelete_Click(object sender, EventArgs e)
{
    MembershipUser su = Membership.GetUser(ddlFullNames.SelectedValue.ToString());
    Membership.DeleteUser(su.UserName, true);
}

Answer 1

Just set a GUI with user id and retrieve the user.

Do you can try this ?

//User id 
Guid userIdToDelete = new Guid("234hg-d23d23j-23d-23d2-2d23d23");
//Delete User with its id
Membership.DeleteUser(Membership.GetUser(userIdToDelete).UserName, true);

Answer 2

Essentially yes the username is required in order to delete, but once you have the user object that's simple enough.

You could also use MembershipUser.ProviderUserKey to get the user, see this link for more info

The correct format is

Membership.DeleteUser("username");

or

Membership.DeleteUser(su.UserName, true);

or more simply
