嗨



字符串值= ConfigurationManager.AppSettings [Key] .tostring();

其中，Key是在Webconfig中指定的.

Hi



String Value = ConfigurationManager.AppSettings[Key].tostring();

where Key is the specified in Webconfig .

您可以按照以下步骤进行操作.

1)在您的项目中创建一个文件夹.例如，名称为"TestFolder".

2)在 Web.config 文件的appSettings部分中定义一个key.

You may follow below steps to do this.

1) Create a Folder in your Project. For Example with Name - "TestFolder".

2) Define a key in appSettings section of your Web.config file.

<appSettings>

<add key="FileUploadFolder" value="TestFolder" />

</appSettings>

3)如下访问key上的value.

3) Access value of above key as below.

string folderFromConfig = ConfigurationManager.AppSettings["FileUploadFolder"].ToString();

FileUpload1.SaveAs(Server.MapPath(folderFromConfig) + FileUpload1.FileName);

string folder_from_config = ConfigurationManager.AppSettings ["FileUploadFolder"].ToString();

FileUpload1.SaveAs(Server.MapPath(folder_from_config)+"\\" + System.IO.Path.GetFileName(FileUpload1.FileName));

< appsettings>

< add key ="FileUploadFolder" value ="TestFolder"/>

</appsettings>

string folder_from_config = ConfigurationManager.AppSettings["FileUploadFolder"].ToString();

FileUpload1.SaveAs(Server.MapPath(folder_from_config) + "\\" + System.IO.Path.GetFileName(FileUpload1.FileName));

<appsettings>

<add key="FileUploadFolder" value="TestFolder" />

</appsettings>
