我正在尝试向表格添加电子邮件,但它丢失了电子邮件中的错误"prashhanth@oberonit.com".我没有看到电子邮件中有任何错误.我添加了其他电子邮件,但不是这个.

列RemovedEmail是varchar(50),null

"字符串或二进制数据将被截断.
该语句已被终止."

 var constultantUser = intensifyDb.ConsultantUsers.FirstOrDefault(x => x.Email == email);

  // Delete the item 
  if (constultantUser != null)
  {
     intensifyDb.DeleteObject(constultantUser);// Save changes 
     intensifyDb.SaveChanges();
   }

   if (!intensifyDb.RemovedEmails.Any(x => x.RemovedEmails == email))
   {
      RemovedEmail consultant = new RemovedEmail
      {
          RemovedEmails = email
      };
      intensifyDb.AddToRemovedEmails(consultant);

此异常通常意味着您的db字段长度不足

我建议在调试器中查看这段代码,并检查字符串的实际长度是多少.

编辑:

我认为它的额外空间将sting复制到编辑器并检查并尝试使用.Trim()

email = email.Trim();

如果修剪不起作用,它可能是一些看不见的Unicode字符

尝试在代码中添加:

var debugCheck = string.Join("", 
            email.Select(c=> String.Format("{0:X2}", Convert.ToInt32(c))))

并将debugCheck的值发送给我,以便我可以检查它.

(这会将电子邮件值转换为十六进制字符串,这将有助于识别可能看起来像空格的额外字符但不会

更新: 所以你实际上有这个字符串(十六进制)707261736868616E7468406F6265726F6E69742E636F6D200B200B200B200B200B200B200B200B2??00B200B200B200B200B200B200B200B200B200B200B200B200B200B200B200B200B200B200B200B20??0B200B200B200B200B200B200B200B200B200B200B200B200B200B200B200B 200B表示Unicode字符'ZERO WIDTH SPACE'(U + 200B)你可以通过使用它删除它

.Replace("\u200B", "");

删除所有unicode空格字符的更通用代码:

Regex.Replace(email, @"^[\s,]+|[\s,]+$", "")
