推荐答案
部署Web应用程序或Web服务是相同的。以下将有所帮助：
IIS特定：
1.在IIS7中：在IIS 7.0上部署ASP.NET网站 [ ^ ]
2.在IIS6中：在IIS上部署网站 [ ^ ]
Deploying a Web Application or Web Service is same. Following will help:
IIS Specific:
1. In IIS7: Deploying ASP.NET Websites on IIS 7.0 [^]
2. In IIS6: Deployment of a Website on IIS[^]
试试这些：
1.启用并将站点的身份验证部分中的 ASP.Net模拟设置为自定义帐户。
2.更改应用程序池的身份，您的网站用于自定义帐户。
3 。将您网站的身份验证部分中的匿名身份验证更改为自定义帐户。
Try these:
1. Enable and set ASP.Net Impersonation in Authentication section of your site to a custom account.
2. Change identity of application pool, your site is using to a custom account.
3. Change Anonymous Authentication in Authentication section of your site to a custom account.
根据给出的信息量，我最好的猜测是它r $>
a）由于网络服务器上的权利问题，无法创建文件
或
b ）无法创建文件，因为目标目录不存在
如果您至少发布了有关错误的一些信息，那么回答会更容易你遇到......
Given the amount of information given, my best guess is that it either
a) Can''t create the file because of rights issues on the web server
or
b) Can''t create the file because the destination directory doesn''t exist
It would be easier to answer if you had posted at least SOME information about the errors you encounter...
