Replacing \n\r in C#

Question

I am having a code where I am getting the below value when I am fetching something from an excel containing some data. The string value contains the characters \n\r as a new line and I need to replace them to put it in a treeview as a new node. The string which I am getting is

"MOVE 'S0500' TO CDA-ERROR-TAG-DATA(CDA-LEVEL-INDEX).\n\rMOVE FND-ERROR-BLOCK TO SAVE-FND-ERROR-BLOCK.\n\rMOVE 'S0500-HOUSEKEEPING' TO FND-ERROR-TAG-DATA.\n\rMOVE LT-PROGRAM-NAME TO FND-PGM-ID.\n\rSET FND-APPL-TYPE-UTILITY TO TRUE.\n\rSET FND-ERROR-TYPE-USER TO TRUE.\n\rMOVE LT-PROGRAM-NAME TO CDA-PROGRAM-ID(CDA-LEVEL-INDEX)."
I need to replace the character \n\r with a character '^'.
The things which I have tried are :-

C#

System.Text.RegularExpressions.Regex.Replace(currentNodeSourceText,Environment.NewLine, "^");
currentNodeSourceText.Replace("//n/r", "^");
currentNodeSourceText.Replace(@"//n/r", "^");
currentNodeSourceText.Replace(@"///n//r", "^");
currentNodeSourceText.Replace(@"//n/r", "^");
currentNodeSourceText = System.Text.RegularExpressions.Regex.Replace(currentNodeSourceText, @"\\n\r", "^");
currentNodeSourceText = System.Text.RegularExpressions.Regex.Replace(currentNodeSourceText, @"\\\n\\r", "^");

None of them is working. Apart from these I tried few more but all seems to be invalid.
Please help.. Thanks in advance.

Are you sure it is \n\r? Normally in Windows the end of line character sequence is the other way around (i.e., \r\n).

Also, 4 of the examples you've shown have the wrong slashes (i.e., you have /n/r where you should use \n\r).

You do not want the @ prefix to the strings as that makes the slash characters regular characters instead of parts of escaped character sequences.

Assuming the original string is as shown, try:

C#

string currentNodeSourceText = "MOVE 'S0500' TO CDA-ERROR-TAG-DATA(CDA-LEVEL-INDEX).\n\rMOVE FND-ERROR-BLOCK TO SAVE-FND-ERROR-BLOCK.\n\rMOVE 'S0500-HOUSEKEEPING' TO FND-ERROR-TAG-DATA.\n\rMOVE LT-PROGRAM-NAME TO FND-PGM-ID.\n\rSET FND-APPL-TYPE-UTILITY TO TRUE.\n\rSET FND-ERROR-TYPE-USER TO TRUE.\n\rMOVE LT-PROGRAM-NAME TO CDA-PROGRAM-ID(CDA-LEVEL-INDEX).";

string newText = currentNodeSourceText.Replace("\n\r", "^");

The Regex is overkill for this substitution. (And remember that the Replace does NOT modify the input string, it returns a new string, so be sure to save the result.)
