Remove a section of text from string c#

Question

I'm using tags in a richtexteditor to specify data fields.

Eg [Start] and [End]

How can I remove a section of text between [Start] and [End] from a string block including the tags?

Is there an easier way rather than using IndexOf and Substring etc?

Update: I'm attempting to use var output = Regex.Replace("[Start]SomeText[End]", @"(?<=[Start]).*(?=[End])", "")

But the pattern does not quite work. It needs to remove everthing between [Start] and [End]

Answer 1

Consider using Regex to replace the text between [Start] and [End]. The following code snippet should help...

var output = Regex.Replace("[Start]SomeText[End]", @"(?<=\[Start\]).*(?=\[End\])", "");

Answer 2

你可以使用正则表达式，但我想不出比搜索文件更容易的东西。
