i know you gave me the points already, but this is the perfected version:<br />
<br />
using using System.Text.RegularExpress<wbr />ions;<br />
on my aspx page i have a text box - txt that the user inputs string to modify in...<br />
<br />
you can just use strings in place of the text box...<br />
<br />
basically says remove anything that is not alphabets - make everything else empty string - &quot;&quot;<br />
<br />
&nbsp;txt.Text = Regex.Replace(txt.Text.ToS<wbr />tring(), @&quot;[^a-zA-Z]&quot;, &quot;&quot;);

Regex return only letters

C# is an object-oriented programming language created in conjunction with Microsoft’s .NET framework. Compilation is usually done into the Microsoft Intermediate Language (MSIL), which is then JIT-compiled to native code (and cached) during execution in the Common Language Runtime (CLR).

A regular expression ("regex") is a sequence of characters that define a search pattern, mainly for use in pattern matching with strings, or string matching, i.e. "find and replace"-like operations. Regular expression processors are found in several search engines, search and replace dialogs of several word processors and text editors, and in the command lines of text processing utilities, such as sed and AWK. Many programming languages provide regular expression capabilities, some built-in, for example Perl, JavaScript, Ruby, AWK, and Tcl, and others via a standard library, for example .NET languages, Java, Python and C++ (since C++11). Most other languages offer regular expressions via a library.
