How to replace very first character only......?
-
I want to replace Dash with a period only once in a string like ABC-XYZ =ABC.XYZ ABCXYZ =ABCXYZ (No Replace) ABC-X-Y-Z =ABC.X-Y-Z A-BC-XYZ =A.BC-XYZ ABCXYZ- =ABCXYZ. I found where the first dash is match using of IndexOF property of string. And RegEx.Replace replace all the found characters I want to replace only first occurrence. But how I can replace only once...?

Hi, u can try this.
string str= "xyz-x-y-z"; int i = str.IndexOf("-"); str = str.Insert(i+1, ".").Remove(i, 1);Thanks, Sun Rays To get something you must have to try once. My Articles

Hi. I hope this work for you. Write this in your some click events. string xNew=""; int j = 1; for (int i = 0; i < TextBox1.Text.Length; i++) { string x = TextBox1.Text.Substring(i, 1); if (x == "-") { if (j == 1) { xNew = xNew + "."; j++; } else { xNew = xNew + x; } } else { xNew = xNew + x; } } Label1.Text = xNew; Small Logic. Thank you.

:laugh:Hi. //Hope this will help you to a Lot for sure..... string xNew=""; int j = 1; for (int i = 0; i < TextBox1.Text.Length; i++) { string x = TextBox1.Text.Substring(i, 1); if (x == "-") { if (j == 1) { xNew = xNew + "."; j++; } else { xNew = xNew + x; } } else { xNew = xNew + x; } } Label1.Text = xNew; }

string str = "ABC-X-Y-Z";
int index = str.IndexOf("-");
str = String.Format("{0}{1}{2}", str.Substring(0, index), ".", str.Substring(index + 1, str.Length - index - 1));Hope it helps.
I will use Google before asking dumb questions
Thanks for your reply. But it will give error in case of string str = ""; Because this input is depend upon the end user So I can-not say the input data in Correct format. Or if dash is not found then it will also give the error. I make new code please let me know this is Ok or not...? ************************************************************** public static string getNewItemName(string actualItemName, string saparaterCharacter) { string valueToReturn = ""; try { int ipos = actualItemName.ToString().IndexOf(saparaterCharacter.ToString()); if (ipos > -1) //That means saparator is not found... { if (saparaterCharacter.ToString().Length == 0) valueToReturn = actualItemName.ToString(); else { string strFirstPart = actualItemName.ToString().Substring(0, ipos).ToString(); string strSecondPart = ""; if (actualItemName.ToString().Length == 0) strSecondPart = actualItemName.ToString().Substring(ipos).ToString(); else strSecondPart = actualItemName.ToString().Substring(ipos + 1).ToString(); valueToReturn = strFirstPart + ":" + strSecondPart; } } else valueToReturn = actualItemName.ToString(); } catch (Exception) { //In Case of any error we are returning the same name valueToReturn = actualItemName.ToString(); } return valueToReturn; } **************************************************************

Hi, here before checking anything you have to check that if(str.Length > 0) { if(str.Contains("-")) { // here write everything.. will not give any error. } }

string str = "ABC-X-Y-Z";
int index = str.IndexOf("-");
if (index>=0) str = str.Substring(0,index)+ "." + str.Substring(index+1);:)

Yet another way:
if ( args.Length > 2 )
{
int index = args [ 0 ].IndexOf ( args [ 1 ] ) ;if ( index >= 0 ) { args \[ 0 \] = (new System.Text.StringBuilder ( args \[ 0 \] )).Replace ( args \[ 1 \] , args \[ 2 \] , index , args \[ 1 \].Length ).ToString() ; } System.Console.WriteLine ( args \[ 0 \] ) ;}

How about this? Thanks for the opportunity.
public static string
Replace
(
string Subject
,
string Old
,
string New
,
ushort MaxReplacements
)
{
System.Text.StringBuilder result = new System.Text.StringBuilder ( Subject.Length ) ;
string[] parts = Subject.Split
(
new string[] { Old }
,
(int) MaxReplacements+1
,
System.StringSplitOptions.None
) ;result.Append ( parts \[ 0 \] ) ; for ( int runner = 1 ; runner < parts.Length ; runner++ ) { result.Append ( New ) ; result.Append ( parts \[ runner \] ) ; } return ( result.ToString() ) ;}
