WCF利用Stream上传大文件

转自别人的文章，学习这个例子，基本上wcf也算入门了，接口用法、系统配置都有了

本文展示了在asp.net中利用wcf的stream方式传输大文件，解决了大文件上传问题。主要是存档方便以后遇到该问题是来查阅。贴出部分代码，如果有疑惑或需要完整代码的请留言 WebForm1.aspx.cs

protected void Button1_Click(object sender, EventArgs e)

        {

            FileData file = new FileData();             file.filename = FileUpload1.FileName;             file.data = FileUpload1.PostedFile.InputStream;             GetDataService c = new GetDataService();             c.UploadFile(file);             Response.Write("文件传输成功！");

        }

IService1

namespace WcfService1

{

    // 注意: 使用“重构”菜单上的“重命名”命令，可以同时更改代码和配置文件中的接口名“IService1”。

    [ServiceContract]

    public interface IGetDataService

    {

        [OperationContract]

        void UploadFile(FileData file);

    }

    [MessageContract]

    public class FileData

    {

        [MessageHeader]

        public string filename;

        [MessageBodyMember]

        public Stream data;

    }

}

Service1.svc

namespace WcfService1

{

    public class GetDataService : IGetDataService

    {

        public void UploadFile(FileData file)

        {

            FileStream fs = new FileStream("D:\\我的项目\\WcfService1\\Files\\" + file.filename, FileMode.OpenOrCreate);

            try

            {

                BinaryReader reader = new BinaryReader(file.data);

                byte[] buffer;

                BinaryWriter writer = new BinaryWriter(fs);

                long offset = fs.Length;

                writer.Seek((int)offset, SeekOrigin.Begin);

                do

                {

                    buffer = reader.ReadBytes(1024);

                    writer.Write(buffer);

                } while (buffer.Length > 0);

                fs.Close();

                file.data.Close();

            }

            catch (Exception e)

            {

                throw new Exception(e.Message);

            }

            finally

            {

                fs.Close();

                file.data.Close();

            }

        }

看到有好几位同学想要源码的，我重新做了个测试工程，经测试只要网络支持，是可以上传几十M以上的大文件的
