Web.config配置文件的加密,解密及读写操作

發(fā)布時間：2025/5/22 编程问答 21 豆豆

生活随笔收集整理的這篇文章主要介紹了 Web.config配置文件的加密,解密及读写操作小編覺得挺不錯的,現(xiàn)在分享給大家,幫大家做個參考.

代碼都比較簡單.不用多做說明:

Code
aspx:
<body>
<form?id="form1"?runat="server">
<div>
<asp:Button?ID="Button1"?runat="server"?Text="加密"?OnClick="Button1_Click"?/>
  
<asp:Button?ID="Button2"?runat="server"?OnClick="Button2_Click"?Text="解密"?/><br?/>
<br?/>
<asp:TextBox?ID="txtConnectionStr"?runat="server"?Width="717px"></asp:TextBox><br?/>
<asp:Button?ID="Button3"?runat="server"?OnClick="Button3_Click"?Text="保存鏈接字串"?/>
 ? ? ? ? ? ? ? ? ? ? ? 
 ? ? ? ? ? ? ? ? ? 
<asp:Button?ID="Button4"?runat="server"?OnClick="Button4_Click"?Text="測試連線"?/></div>
</form>
</body>

aspx.cs
protected?void?Page_Load(object?sender,?EventArgs?e)
{

}
protected?void?Button1_Click(object?sender,?EventArgs?e)
{
Configuration?config?=?WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath);
ConfigurationSection?section?=?config.Sections["connectionStrings"];
if?(!section.SectionInformation.IsProtected)
{
section.SectionInformation.ProtectSection("RsaProtectedConfigurationProvider");
section.SectionInformation.ForceSave?=?true;
config.Save(ConfigurationSaveMode.Modified);
}
}
protected?void?Button2_Click(object?sender,?EventArgs?e)
{
Configuration?config?=?WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath);
ConfigurationSection?section?=?config.ConnectionStrings;
if?(section.SectionInformation.IsProtected)
{
section.SectionInformation.UnprotectSection();
section.SectionInformation.ForceSave?=?true;
config.Save(ConfigurationSaveMode.Modified);
}
}
protected?void?Button4_Click(object?sender,?EventArgs?e)
{
string?str?=?ConfigurationManager.ConnectionStrings["PEP"].ToString();
Response.Write(ConnectionTesting(str));
}
protected?void?Button3_Click(object?sender,?EventArgs?e)
{
//測試數(shù)據(jù)庫鏈接字串是否正確.
if?(ConnectionTesting(txtConnectionStr.Text)?==?"鏈接字串設置成功")
{
//保存當前鏈接字串到config
Configuration?config?=?WebConfigurationManager.OpenWebConfiguration(Request.ApplicationPath);
ConnectionStringsSection?section?=?(ConnectionStringsSection)config.GetSection("connectionStrings");
section.ConnectionStrings["PEP"].ConnectionString?=?txtConnectionStr.Text;
config.Save(ConfigurationSaveMode.Modified);
}
}

protected?string?ConnectionTesting(string?connstr)
{
string?msg?=?"";
string?str?=?string.IsNullOrEmpty(connstr)???""?:?connstr;
SqlConnection?conn?=?new?SqlConnection(str);
try
{
conn.Open();
msg?=?"鏈接字串設置成功";
}
catch?(Exception?ex)
{
msg?=?ex.Message.ToString();
}
finally
{
conn.Close();
}

return?msg;
}
