图像的正则表达式？ [英] Regular Expression for image?

问题描述

我必须使用文件up-loader将图像上传到DB中。我已使用下面给出的代码，但它不起作用。如果我上传任何也插入数据库的pdf或doc文件，也会显示错误消息。如果文件不是图像格式，我想停止插入。帮我找一个合适的解决方案。谢谢。



ASPX：

 <   asp：FileUpload     ID   =  PhotoUpload1    runat   =  server    ForeColor   = ＃999999    /  >  <   asp：RegularExpressionValidator     ID   =  RegularExpressionValidator6    runat   =  server    ErrorMessage   =  * jpeg，gif，png    ControlToValidate   =  PhotoUpload1    ForeColor   = 红色    ValidationExpression   = 。* \。（[gG] [iI] [fF] | [jJ] [pP] [gG] | [jJ] [pP] [eE] [gG] | [bB] [mM] [pP]）$ >  <   / asp：RegularExpressionValidator  >
