关于sl+wcf上传文件的问题

Question

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

        }
    }
}

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。

Answer 1

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
