I want to convert the input alphanumeric data which we take from the textbox to the uppercase only for alphabets.

C#

protected void Page_Load(object sender, EventArgs e)

  {
      emp_mid= txtEmpmid.Text;

  }

C#

protected void btnShowGraph_Click(object sender, EventArgs e)
{




    ViewState["EmpDetails"] = GetRptDetails(txtEmpmid.Text.ToString());
    string details = ViewState["EmpDetails"].ToString();


    string sourcepath = @"C:\Inetpub\wwwroot\Osource_local_Trial_Rushikesh\Code\PM\Roots\js\example1.js";

    string destinationpath = @"C:\Inetpub\wwwroot\Osource_local_Trial_Rushikesh\Code\PM\Roots\GraphLoginData";

    string filename = Session["E_EMPNAME"].ToString() + ".js";
    string destFile = System.IO.Path.Combine(destinationpath, filename);

    if (File.Exists(destFile))
    {
        File.Delete(destFile);

    }
    ReplaceTextInFile(sourcepath, destFile, "REPLACE_CODE", details);


    string JsFileName = "js/" + filename ;
    Literal script = new Literal();
    script.Text = string.Format(@"<script src=""{0}"" type=""text/javascript""></script>", JsFileName);
    Page.Header.Controls.Add(script);

}

Solution 1

try to use

C#

emp_mid= txtEmpmid.Text.ToUpper();

Remember one thing, numeric value is not having any type like upper or lower, so if you apply ToUpper on numeric value it simply return same value...

Dear Sir,

r u sure about dis.coz id read sumvhr dat toupper() will convert the numbers into an equivalent aplhabet.Please inform.Thanks

Tejas Vaishnav 10-Mar-14 8:31am

yes, number is not having any different value like Upper or Lower case.

if you provide value like "12$RerIuop*" then ToUpper() will return like this "12$RERIUOP*"

Most likely so, but you cannot be 100% sure. Please see my answer and my comment to Solution 2.
Culture parameter should be used.

Solution 3

It looks like you need to use the method String.ToUpper(CultureInfo):

C#

string myString = someString.ToUpper(System.Globalization.CultureInfo.InvariantCulture);

This way, you can be sure that even if some culture-specific form of digits is used, they won't be involved.

Please don't use txtspk here: you have a keyboard, so use it.

Yes, I'm sure: ToUpper and ToLower only affect alphabetic characters, they do not affect numerics or punctuation.

Sergey Alexandrovich Kryukov 10-Mar-14 10:26am

No, you cannot be 100% sure, in general case. This is because the notion of "digit" can include some culture-dependent forms of digits, such as traditional Arabic. Even though they hardy can have upper and lower form, who knows. So, even though your advice will work in all or nearly all cases, to be on safe side, it's better to use neutral culture. Or, if the target culture is known and always the same, this particular culture. Please see my answer.
