大文件上传到服务器报错的问题

最近遇见了个大文件上传到服务器报错的问题；我使用的是FileUpload控件上传的

开始用的是SaveAs()和WebClient的方法，结果本地测试可以上传，一发布的服务器就出错，配置文件也写了<httpRuntime maxRequestLength="2058000" executionTimeout="90000" useFullyQualifiedRedirectUrl="false" requestLengthDiskThreshold="8192"/>但是还是不行，

郁闷了我好几天！

今天突然想到了用文件流上传FileStream

结果还真行了！

代码很简单

1.需要配置web.config里写上限制文件上传的大小就上面的那段代码；

2.在aspx.cs的文件里写：

Boolean IsReady = false;

        if (this.FileUpload1.PostedFile != null && this.FileUpload1.PostedFile.ContentLength > 0)

        {

            string path = this.Server.MapPath(@"Uploads");

            string fileName = Path.GetFileName(this.FileUpload1.PostedFile.FileName);

            int ContentLength = this.FileUpload1.PostedFile.ContentLength;

            int UploadedLength = 0;

            //uploadInfo.ContentLength = this.FileUpload1.PostedFile.ContentLength;

            //uploadInfo.FileName = fileName;

            //uploadInfo.UploadedLength = 0;

            //uploadInfo.IsReady = true;

            int bufferSize =1000;

            byte[] buffer = new byte[bufferSize];

            using (FileStream fs = new FileStream(Path.Combine(path, fileName), FileMode.Create))

            {

                while (UploadedLength < ContentLength)

                {

                    int bytes = this.FileUpload1.PostedFile.InputStream.Read(buffer, 0, bufferSize);

                    fs.Write(buffer, 0, bytes);

                    UploadedLength += bytes;

                }

                IsReady = true;

            }

            if(IsReady)

            {

                Response.Redirect("Default2.aspx");

            }

发布到服务器上后在本地上传大文件就没有错误了！

不过上传速度有点慢：一个400M的文件要传大概2分钟！
