                         +"-"+empPreWork.to_date+empPreWork.pre_work_description_sve));

C#

public string firstcharacterupper(string str)
        {
            return CultureInfo.CurrentCulture.TextInfo.ToTitleCase(str.ToLower());
        }

This code makes the first letter Uppercase. But for example Description if i will write some text every letter will get big but i only want the first character in description to be upcase
right now for example , description gets like this

Hi My Name Is Bill but i want to have Hi my name is bill

Solution 1

Try this

C#

static string UppercaseFirst(string s)
   {
   // Check for empty string.
   if (string.IsNullOrEmpty(s))
   {
       return string.Empty;
   }
   // Return char and concat substring.
   return char.ToUpper(s[0]) + s.Substring(1).ToLower();
   }

Call the Method

C#

UppercaseFirst("Codeproject");

Hope this helps

Why are you defining a LowercaseFirst method and then invoking a UppercaseFirst one? :-D
By the way, my 5.

OP asked for Uppercase but did u read the last sentence?'Hi My Name Is Bill but i want to have Hi my name is bill'

You (but not your code) are right. He wants the first letter capitalized while the rest of the string should be lower case.

Your call example is unfortunate (the input string is already a good output one).
Moreover, in your code, you should change s.Substring(1) to s.Substring(1).ToLower().

This code returns empty string for null input string, which is not nice. It's the best to return null for null, empty for empty, and lo-case first character for the rest of the cases...
