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

C#

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";
                   }
               }

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

Give any solution for this

What about:

C#

Convert.ToInt16(details.ToString())

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

Hi,

You need to convert the StringBuilder back to a string

C#

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

           string detailsStr = details.ToString();

           if (detailsStr == "0")
           {

           }

Regards,
T

Solution 1

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