C＃从Readline输入中删除选项卡

Question

I am inputting lines using the StreamReader's ReadLine. However for user friendliness in terms of reading the files outside of the program, I want to add tabbing. But I need to remove any tabbing when the files are being read in the program.

How can this be achieved? I have considered using Trim but I don't know if that will work.

Answer 1

Use string.Trim with the specified characters if you want starting and trailing tabs:

var trimmed = streamReader.ReadLine().Trim('\t');

Or Regex.Replace if tabs are also in the middle:

string trimmed = Regex.Replace(lineWithTabs, @"\t", "");

Answer 2

You can use String.Replace :

string fileContent = File.ReadAllText("path");
fileContent = fileContent.Replace('\t', ' ');

Of course that works also for every line returned by ReadLine .
