دوست من، این تابع برای ایجاد کاربر جدید در سیستم Membership مایکروسافت استفاده میشه. Overload های مختلفی داره که ساده ترینش به این شکل هست:
public static MembershipUser CreateUser(
string username,
string password
)
کافیه یک نام کاربری و یک پسورد به این تابع پاس بدی تا در صورت امکان کاربر جدید را به دیتابیس اضافه کنه و اونو به صورت خروجی از نوع MembershipUser برگردونه، در صورتی که به هر علتی خطایی اتفاق بیفته یک Exeption از نوع MembershipCreateUserException تولید میشه. اما اگر بخوایی به جای مدیریت خطا از وضعیت عملیات و نتیجه اطلاع پیدا کنی می تونی از Overload های سوم یا چهارم این تابع استفاده کنی که یک پارامتر خروجی به نام MembershipCreateStatus میگیره و وضعیت ایجاد کاربر را از این طریق بر می گردونه:
public static MembershipUser CreateUser(
string username,
string password,
string email,
string passwordQuestion,
string passwordAnswer,
bool isApproved,
Object providerUserKey,
out MembershipCreateStatus status
)
این هم یک مثال:

}
else

}
}
catch

}
}
public string GetErrorMessage(MembershipCreateStatus status)

switch (status)
