How to replace a string in a string except first occurrence

Question

How to replace a string in a string except first occurrence?

e.g. C:\\Test-Processed\1-Processed\2-Processed should output

C:\\Test-Processed\1\2

Answer 1

Something like following:

string originalStr = "C:\\Test-Processed\\1-Processed\\2-Processed";
string temp = "-Processed";
string str = originalStr.Substring(0, originalStr.IndexOf(temp) + temp.Length);
originalStr = str + originalStr.Substring(str.Length).Replace(temp, "");

originalStr will be:

originalStr = "C:\\Test-Processed\\1\\2"
