Hi <br />
<br />
I am working on ASP.net2.0, C#<br />
<br />
I have a regular expression which checks if file is xls or not<br />
<br />
It works fine, if we sellect the file from local system or map drive<br />
<br />
But it does not work if we take the file from map drive<br />
<br />
like<br />
\\barney\Testing\Excel Example_R1.xls<br />
<br />
My RegularExpressionValidator<wbr /> is<br />
<br />
&lt;asp:RegularExpressionVali<wbr />dator id=&quot;RegExpFile&quot; runat=&quot;server&quot; ErrorMessage=&quot; &quot;<br />
ControlToValidate=&quot;FileUpl<wbr />oad1&quot; ValidationExpression=&quot;^.+\<wbr />.((xls)|(X<wbr />LS)|(Xls))<wbr />$&quot;&gt;&lt;/asp:R<wbr />egularExpr<wbr />essionVali<wbr />dator&gt;<br />
<br />
<br />
Please help <br />
<br />
This is very urgent for me

Excel file checking using RegularExpressionValidator

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).
