Over the years, many programming languages and tools have included support for C # server-side expressions. The .NET basic class library contains a namespace and a series of classes that take full advantage of regular expressions, and they are all compatible with future Perl 5 regular expressions.

In addition, the regexp class can perform some other functions, such as associating patterns from right to left and editing expressions.

The knowledge of regular expressions may be one of the things that many programmers often learn and forget. In this article, we will assume that you have mastered the use of regular expressions, especially in Perl 5. The .NET regexp class is a superset of expressions in Perl 5, so in theory it would be a good starting point.

Examples of getting started are as follows

/ / verify string strFileName = "S_123456_200701.zip" System.Text.RegularExpressions.Regex strReg = new System.Text.RegularExpressions.Regex (@ "^ S\ d {6} _\ d {6}\ .zip $"); if (strReg.IsMatch (strFileName)) {Response.Write ("ok");} else {Response.Write ("sorry") } Thank you for your reading. The above is the content of "what is a C# server-side expression". After the study of this article, I believe you have a deeper understanding of what a C# server-side expression is. The specific use of the situation also needs to be verified by practice. Here is, the editor will push for you more related knowledge points of the article, welcome to follow!
