Replace a Substring with Another Substring in a String

Question

0.00/5 (No votes)

See more:

I have a string like

output="'TransactionSourceID !='8' and GeneralLedger_SubTransactionType_CnfgLocale.SubTransactionType != '1'";

I need to remove the single quote before TransactionSourceID alone.

How do I do it ?

I tried

C#

if(output.Contains("'TransactionSourceID"))
                            output.Replace("\'TransactionSourceID","TransactionSourceID");

and

C#

if(output.Contains("'TransactionSourceID"))
                            output.Replace("'TransactionSourceID","TransactionSourceID");

But it didn't work.

I cant use index of the character because the length of the string and the position of "TransactionSourceID" may vary.

Any solutions ??

That should be:

C#

if(output.Contains("'TransactionSourceID"))
  output = output.Replace("\'TransactionSourceID","TransactionSourceID");

or simply:

C#

output = output.Replace("\'TransactionSourceID","TransactionSourceID");

Solution 1

If you mean by "didn't work" that your changed string wasn't available via the output variable, then just try to assign it:

C#

output = output.Replace(YourCode);

"[String.Replace] does not modify the value of the current instance. Instead, it returns a new string in which all occurrences of oldValue are replaced by newValue." (from the linked MSDN page).
