C# Unrecognized escape sequence

Question

I have following Regex on C# and its causing Error: C# Unrecognized escape sequence on \w \. \/ .

string reg = "<a href=\"[\w\.\/:]+\" target=\"_blank\">.?<img src=\"(?<imgurl>\w\.\/:])+\"";
Regex regex = new Regex(reg);

I also tried

string reg = @"<a href="[w./:]+" target=\"_blank\">.?<img src="(?<imgurl>w./:])+"";

But this way the string "ends" at href=" "-char

Can anyone help me please?

Use "" to escape quotations when using the @ literal.
