hi guyz我去了这个错误代码:执行命令定义时发生错误。有关详细信息,请参阅内部异常。,将我的文本搜索到数据库..
private bool IsValidRegisterNewAcct(string acctname, string dispname, string email, string password)
{
var crypto = new SimpleCrypto.PBKDF2();
bool IsValid = false;
IsValidErrorMessage = "";
IsValidErrorMessageInt = 0;
string Newacctname = crypto.Compute(acctname.ToString());
//try
//{
using (var db = new MainDbContext())
{
//db.Connection.Open();
var user = db.user.FirstOrDefault(u => u.AcctNameSalt == Newacctname);
//var user = db.osoa_user.FirstOrDefault(u => u.Email == email);
if (user != null)
{
IsValid = false;
//db.Connection.Close();
IsValidErrorMessage = "Account Name already Exist!";
}
else
{
var InsertNewAcctName = db.osoa_user.CreateObject();
InsertNewAcctName.UserId = Convert.ToString( Guid.NewGuid());
InsertNewAcctName.AcctName = acctname;
InsertNewAcctName.AcctNameSalt = crypto.Compute(acctname);
InsertNewAcctName.DisplayName = dispname;
InsertNewAcctName.Email = email;
InsertNewAcctName.EmailSalt = crypto.Compute(email);
InsertNewAcctName.Password = crypto.Compute(password);
InsertNewAcctName.PasswordSalt = crypto.Salt;
InsertNewAcctName.UserLevel = 2;
db.user.AddObject(InsertNewAcctName);
db.SaveChanges();
//db.Connection.Close();
IsValid = true;
}
}
/*
}
catch (Exception e)
{
IsValidErrorMessageInt = 1;
IsValidErrorMessage = e.Message + ". Pls. contact your Administrator.";
IsValid = false;
}
*/
return IsValid;
}
并且错误指向此代码:
var user = db.user.FirstOrDefault(u => u.AcctNameSalt == Newacctname);
更新关于内部异常。我不知道是否给你正确的..我试着使用这段代码:
try
{
}
catch (Exception e)
{
IsValidErrorMessageInt = 1;
IsValidErrorMessage = e.InnerException + ". Pls. contact your Administrator.";
IsValid = false;
}

从您的内部异常看起来好像您的MainDbContext
已经与您的数据库不同步(看起来Extent1
有一个在数据库中不存在的列)。
尝试从模型中删除该属性,然后重试。
