我使用sl+wcf上传文件，用vs能正常运行，但是部署到iis
using System;
using System.Collections.Generic;
using System.Linq;
using System.Runtime.Serialization;
using System.ServiceModel;
using System.Text;
using System.ServiceModel.Activation;
namespace UploadTest.Web
{
[ServiceContract(Namespace = "")]
[AspNetCompatibilityRequirements(RequirementsMode = AspNetCompatibilityRequirementsMode.Allowed)]
public class UploadService
{
[OperationContract]
public void ActionUpload(string fileName, byte[] fileContext, bool isAppend)
{
string uploadFolder = System.Web.Hosting.HostingEnvironment.MapPath("~/upload");
if (!System.IO.Directory.Exists(uploadFolder))
{
System.IO.Directory.CreateDirectory(uploadFolder);
}
System.IO.FileMode fileMode = System.IO.FileMode.Create;
if (isAppend)
{
fileMode = System.IO.FileMode.Append;
}
using (System.IO.FileStream fs = new System.IO.FileStream(uploadFolder + @"\" + fileName, fileMode, System.IO.FileAccess.Write))
{
fs.Write(fileContext, 0, fileContext.Length);
}
}
}
}
以上是wcf文件的代码

if (uploadFile.FileByte.Count == 0)
{
HtmlElement element = HtmlPage.Document.GetElementById("GetUploadFileName");
// element.SetAttribute("value", uploadFile.FileName);
button1.Content = "恭喜您，上传成功";
}
else
{
(sender as UploadServiceClient).ActionUploadAsync(uploadFile.FileName, uploadFile.FileByte[0], true, uploadFile);
double progressBar = uploadFile.FileCompletedByte / uploadFile.FileSize;
button1.Content = progressBar.ToString("0%");
}
}
}
catch (Exception ex)

}
以上为xamp中的代码
后就不正常了，求高手讲解，代码贴出来了，谢谢各位高手了。

IIS中你需要在某个目录写文件（System.IO.FileAccess.Write），把这个目录的权限 赋予IIS的运行账号Network Services 就行了
VS中运行时使用的是你当前登录的账号权限因此是可以的

这位兄台，我按照你的办法做了，还是不行，不知道还有其它什么原因呢？
不会吧，你用事件查看器看看记录了什么内容，这里应该有线索
