ASP.NET-------MD5加密设计

简单的对文本进行Md5加密小工具效果如下：

App code中添加Md5Help类：

  
    

   
     public
   
      
   
     static
   
      
   
     class
   
      MD5Helper
{
 
   
     public
   
      
   
     static
   
      
   
     string
   
      MD5Hash(
   
     this
   
      
   
     string
   
      s)
   
     //
   
     扩展方法
   
     

   
      {
 
   
     return
   
      System.Web.Security.FormsAuthentication.HashPasswordForStoringInConfigFile(s,
   
     "
   
     md5
   
     "
   
     );
 }

 
   
     private
   
      
   
     static
   
      
   
     string
   
      str;
 
   
     public
   
      
   
     static
   
      
   
     string
   
      MD5Str
 {
 
   
     get
   
     
 {
 
   
     return
   
      str.MD5Hash();
   
     //
   
     调用扩展方法
   
     

   
      }
 
   
     set
   
      {str 
   
     =
   
      value;}
 }
}
  
    

Md5.cs代码：

  
    

   
     using
   
      System;

   
     using
   
      System.Collections.Generic;

   
     using
   
      System.Linq;

   
     using
   
      System.Web;

   
     using
   
      System.Web.UI;

   
     using
   
      System.Web.UI.WebControls;


   
     namespace
   
      MD5
{
 
   
     public
   
      
   
     partial
   
      
   
     class
   
      Md5 : System.Web.UI.Page
 {
 
   
     protected
   
      
   
     void
   
      Page_Load(
   
     object
   
      sender, EventArgs e)
 {

 }

 
   
     protected
   
      
   
     void
   
      btnMD5_Click(
   
     object
   
      sender, EventArgs e)
 {
 MD5Helper.MD5Str 
   
     =
   
      
   
     this
   
     .txtText.Text;
 
   
     this
   
     .lblResult.Text 
   
     =
   
      MD5Helper.MD5Str;
 }
 }
}
  
    

前台布局：

  
    

   
     <
   
     body
   
     >
   
     
 
   
     <
   
     form 
   
     id
   
     ="form1"
   
      runat
   
     ="server"
   
     >
   
     
 
   
     <
   
     div 
   
     style
   
     ="text-align:center"
   
     >
   
     
 MD5加密文本
 
   
     <
   
     asp:TextBox 
   
     runat
   
     ="server"
   
      ID
   
     ="txtText"
   
     ></
   
     asp:TextBox
   
     >
   
     
 
   
     <
   
     asp:Button 
   
     runat
   
     ="server"
   
      ID
   
     ="btnMD5"
   
      Text
   
     ="加密"
   
      onclick
   
     ="btnMD5_Click"
   
      
   
     />
   
     
 
   
     <
   
     br 
   
     />
   
     
 加密后文本：
   
     <
   
     asp:Label 
   
     runat
   
     ="server"
   
      ID
   
     ="lblResult"
   
     ></
   
     asp:Label
   
     >
   
     
 
   
     </
   
     div
   
     >
   
     
 
   
     </
   
     form
   
     >
   
     

   
     </
   
     body
   
     >
