当stringbuilder进行转换时显示错误 [英] Error displays when stringbuilder turns to convert

问题描述

我有C#编码...

在此我使用stringbuilder ...因此，当stringbuilder值转换为int时，它会显示一些错误，例如
"无法将类型为"System.Text.StringBuilder"的对象转换为类型为"System.IConvertible".

我的编码是这个

I have C# coding...

In this I using stringbuilder...So when stringbuilder value converts to int it shows some error like
""Unable to cast object of type ''System.Text.StringBuilder'' to type ''System.IConvertible"".

my coding is this

if (username.Length > 0)
               {
                   StringBuilder details = objectfororderdetails.GetUsernamelocked(UserName, lockedout);
                   lbllockuser.Text = "Username and his/her Restaurants Successfully locked";
                   if (Convert.ToInt16(details) == 0)
                   {
                       txtlockuser.Text = null;
                       lbllockuser.Text = "Username and his/her Restaurants already locked";
                   }
               }

当运行时出现if(Convert.ToInt16(details)== 0)时，显示如我上面提到的错误.


为此解决方案提供任何解决方案

when runtime comes in if(Convert.ToInt16(details) == 0) it shows error like i mentioned above.


Give any solution for this

推荐答案

尝试直接转换 details.ToString()而不是details .
示例-if (Convert.ToInt16(details.ToString()) == 0)

Try converting details.ToString() instead of details directly.
Example - if (Convert.ToInt16(details.ToString()) == 0)

有关:

Convert.ToInt16(details.ToString())

请记住一次，stringbuilder不是字符串，您不能将其用作字符串.

Remember for once, stringbuilder is not string, you cannot use it as a string.

您需要将StringBuilder转换回字符串

Hi,

You need to convert the StringBuilder back to a string

StringBuilder details = new StringBuilder();
           details.Append("0");

           string detailsStr = details.ToString();

           if (detailsStr == "0")
           {

           }

问候，
