       SB.Appendline("ToolBarCollection.Add Arcid.");

File.WriteAllText(@"C:\temp\IDs.txt",SB.ToString);

Start by helping yourself and tell us what error messages and where.
Try to explain what the code is supposed to do.

Why everyone seems to think that the exact error message, as well as the place where the error occured, are not relevant facts? :)

imho anyone who hasn't learned to set break-points and isolate where errors are occurring is ... uninformed

It seems like you have mixed up ReadAllText and ReadAllLines.
You can use either or, but the in first case you get all text in one string and cannot perform a foreach loop on string level. ReadAllLines on the other hand will return an array of strings, one string for each line in the file.

If the file is relatively small you can use ReadAllText and do the search and replace on the single string like

C#

string inputText = File.ReadAllText(@"C:\temp\ArcId.txt");
string outputText = inputText.Replace("Toolbar()", "Toolbar");
File.WriteAllText(@"C:\temp\IDs.txt", outputText);

Not sure that this replacement is exactly what you want to do, but you didn't give that information.

You can also read line by line:

C#

StringBuilder outputText = new StringBuilder();
foreach (string line in File.ReadAllLines(@"C:\temp\ArcId.txt"))
{
    outputText.Append(line.Replace("Toolbar()", "Toolbar"));
}
File.WriteAllText(@"C:\temp\IDs.txt", outputText.ToString());
