有人可以帮我使用正则表达式吗？

Question

I am trying to get everything between quotations. What will be between the quotations is file locations. So it will be like "C:\\Users\\Documents and Settings\\Pictures\\mypic.bmp" The regex I am currently using is:

   "([""'])(?:(?=(\\?))\2.)*?\1"

It works to get numbers and letters except it splits it at the backslash. Can someone help me out so I can match the full string?

Thanks in advance.

Answer 1

I would go with:

@"""\s*(.*?)\s*"""

Sample code I used to test it:

    protected void btnSubmit_Click(object sender, EventArgs e)
    {
        Match match = Regex.Match(txtString.Text, @"""\s*(.*?)\s*""",
            RegexOptions.IgnoreCase);

        if (match.Success)
        {
            string key = match.Groups[1].Value;
            lblFinal.Text = key;
        }
    }

Can we fix my negative votes? ;)

Answer 2

You can use the following regex (quoting in C# string literal):

string regexPattern = "\\\"(.+?)\\\"";

or

string regexPattern = @"\""(.+?)\""";

Without C# literal escaping

\"(.+?)\"

This way the matched group will be the string within the quotations

If testing at http://derekslager.com/blog/posts/2007/09/a-better-dotnet-regular-expression-tester.ashx

Source

"C:\Users\Documents and Settings\Pictures\mypic.bmp"

Pattern

\"(.+?)\"

Result

C:\Users\Documents and Settings\Pictures\mypic.bmp
