将文件上传到WCF [英] Uploading files to wcf

问题描述

我需要使用流媒体上传文件.当用户在浏览器中选择文件时，该文件将转换为流
如下所示.


客户端代码:

I need to upload files using streaming. when a user selected a file in browser it is converted to stream
is is done as follows.


client side code:

if (FileUpload1.HasFile)
        { 
            System.IO.FileInfo fileInfo = new System.IO.FileInfo(FileUpload1.PostedFile.FileName);
            FileTrasferServiceReference.TransferServiceClient clientUpload = new TransferServiceClient();
            using (System.IO.FileStream stream = new System.IO.FileStream(FileUpload1.PostedFile.FileName, System.IO.FileMode.Open, System.IO.FileAccess.Read))
            {                
                clientUpload.UploadFile(stream); 
            }
        } 

Wcf服务端代码:

Wcf Service side code:

public void UploadFile(System.IO.Stream FileByteStream)
    {
        FileStream targetStream = null;
        Stream sourceStream =  FileByteStream;

        string uploadFolder = @"C:\upload\";
        //string filename = request.FileMetaData.Filename;
        string filePath = Path.Combine(uploadFolder, "xyz.zip");

        using (targetStream = new FileStream(filePath, FileMode.Create, FileAccess.Write, FileShare.None))
        {
            //read from the input stream in 4K chunks
            //and save to output stream
            const int bufferLen = 4096;
            byte[] buffer = new byte[bufferLen];
            int count = 0;
            while ((count = sourceStream.Read(buffer, 0, bufferLen)) > 0)
            {
                targetStream.Write(buffer, 0, count);
            }
            targetStream.Close();
            sourceStream.Close();
        }

    } 

文件未上传，以上代码正确还是错误?

the files are not being uploaded, is the above code correct or wrong? if not correct can some one provide sample code of it.

推荐答案

我建​​议您将try/catch块放在所有内容周围，然后在调试器下运行它. br/>
可能是您的WCF连接未建立.

I recommend that you put try/catch blocks around everything, and then run it under the debugger.

It might be that your WCF connection isn''t being established.

这是在评论中发布评论的同一个人，我无法正确添加代码，所以我在这里添加.

我已经建立了wcf连接

this is the same person who posted the comment in the comment a above i was not able add the code properly so i am adding it here.

I have established the wcf connection
