WCF利用Stream上传大文件

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
