hello i'm doing a hex to ascii converter. but now the problem is whenever it's converted, the hex code would be in front of the ASCII code.

private void convertButton_Click(object sender, EventArgs e)
{
asciiTextBox.Text = HexString2Ascii(hexTextBox.Text);
}

Input: 4153434949
Output: 4153434949ASCII

i know the problem lies with the hexTextBox.Text. but how do i remove the 4153434949 in front of the converted one?

What is the definition of the function HexString2Ascii?

What is the definition of the function HexString2Ascii?

private string HexString2Ascii(string HexString)
        {
            StringBuilder Sb = new StringBuilder(hexTextBox.Text);
            for (int intI = 0; intI <= hexTextBox.Text.Length - 2; intI += 2)
            {
                Sb.Append(Convert.ToString(Convert.ToChar(Int32.Parse(HexString.Substring(intI, 2), System.Globalization.NumberStyles.HexNumber))));
            }
            return Sb.ToString();
        }

Can you explain the purpose of line 3?

Looks like java to me.

yeah c# is like java. object oriented.

I think it is C# and indeed the original text is stored in that StringBuilder first and
next the ASCII characters are appended do it. Line #3 should instantiate an
empty StringBuilder instead.

You're welcome but next time make sure you post your C# questions in the .NET forum.
This is a C and C++ forum and has (almost) nothing to do with C# (nor Java).
