C#

public static class PatternFileAndFolder
{
    private static string _lote = @"\LOT_";
    private static string _documento = @"\DOC_";

    public static string LotePattern
    {
        get{return _lote.PadRight(8, '0') ;}
    }

    public static string DocumentoPattern
    {
        get { return _documento.PadRight(8, '0'); }
    }
}

Solution 2

Try this:

C#

private static string _lote = @"\LOT_00";

private static string LotePattern(string stringToPad)
{
    return _lote + ((stringToPad.Length == 1) ? "0" : "") + stringToPad;
}

Test:

C#

string test1 = "1";
string test2 = "11";

string result1 = LotePattern(test1);
string result2 = LotePattern(test2);

Try the below method

C#

private string AddLeadingZeros(int totalLength, string originalNumber)
        {
            string leadingZeros = string.Empty;
            int counter = 0;
            try
            {
                counter = totalLength - originalNumber.Length;
                for (int leadingZeroCount = 0; leadingZeroCount < counter; leadingZeroCount++)
                {
                    leadingZeros += "0";
                }
                originalNumber = leadingZeros + originalNumber;
            }
            catch (Exception ex)
            { LogExceptionDetails(ex); }
            return originalNumber;
        }

In the method you will need to pass two parameters the first one is the total length and the second one is the number. Basing on the difference of lengths it will calculate the number of zero's to be added to the string.

For example let us consider that the total length is "4" and the original string which you are passing is "1". Now calculate the difference that is total length - length of the original string (4 - 1) then it will add three zero's to the original string. If you consider your original value as "01" the it will add two zero's and so on.

Hi,
Just try following:

C#

int txtVal = 11;
string sz = "\\LOT_" + txtVal.ToString("0000");

Solution 1

How about something like:

C#

string _lote = @"\LOT_{0:0000}";
string x = System.String.Format ( _lote , 11 ) ;

No work for me... When I put value on textbox the result is same for question

Look
private static string _lote = @"\LOT_{0:0000}";
private static string _documento = @"\DOC_";
private static string x = string.Format(_lote, 8);

public static string LotePattern
{
get { return x; }
}

public static string DocumentoPattern
{
get { return _documento.PadRight(8, '0'); }

}

Won't work with strings. Do you need to support more than numeric values? If not, parse or use a NumericUpDown rather than a TextBox.
