CSharp C# Regular Expression RegExp for SEARCH and REPLACE with examples Notepad++ and Visual Studio

[See also "CSharp C# Regular Expression REPLACE example"]

Base CLK example using Notepad++ (note that it will not work if file is not saved...):

Console.WriteLine("Stuff n more stuff");

Search:  (Console.?WriteLine\()(\").*(\"\);)

replace: \1\2dog\3

Example:  Find Console.WriteLine items with "," and {} references.  Replace Console.WriteLine with LogInforAndConsole and surround full text, comma, and value in string or variable with the String.Format function.  And ignore non-comma signatures.

Before:

Console.WriteLine("Stuff n more stuff={0}", "something else");

Console.WriteLine("Hello all!");

Console.WriteLine("Stuff n more stuff={0}", myVar);

Search:  (Console.?WriteLine\()(\")(.*,.*)(\);)

                       \1                      \2   \3  \4

replace: LogInfoAndConsole\(string.Format\(\2\3\)\4

replace: LogInfoAndConsole(string.Format($2$3)$4    ($ instead of \# and no slash(escape) in front of parenthesis with C# and Visual Studio search)

After:

LogInfoAndConsole(string.Format("Stuff n more stuff={0}", "something else"));

Console.WriteLine("Hello all!");

LogInfoAndConsole(string.Format("Stuff n more stuff={0}", myVar));

Example:  Find all simple Console.Writeline items and replace Console.WriteLine with LogInforAndConsole.

Before:

 Console.WriteLine("Hello all!");

Search:  (Console.?WriteLine\()(\")(.*)(\);)

                       \1                      \2   \3  \4

replace: LogInfoAndConsole\(\2\3\4

replace: LogInfoAndConsole(s$2$3$4    ($ instead of \# and no slash(escape) in front of parenthesis with C# and Visual Studio search)

After:

LogInfoAndConsole("Hello all!");

Example: Find all Console.WriteLine with variable only values and substitute Console.WriteLine with LogInfoAndConsole.

Before:

Console.WriteLine(verificationErrors.ToString());

Console.WriteLine(myVar);

Search:  (Console.?WriteLine\()(.*)(\);)

                       \1                        \2   \3

replace: LogInfoAndConsole\(\2\3

replace: LogInfoAndConsole($2$3    ($ instead of \# and no slash(escape) in front of parenthesis with C# and Visual Studio search)

After:

LogInfoAndConsole(verificationErrors.ToString());

LogInfoAndConsole(myVar);
