轉自別人的文章,學習這個例子,基本上wcf也算入門了,接口用法、系統配置都有了
本文展示了在asp.net中利用wcf的stream方式傳輸大文件,解決了大文件上傳問題。主要是存檔方便以后遇到該問題是來查閱。貼出部分代碼,如果有疑惑或需要完整代碼的請留言
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("文件傳輸成功!"); }
IService1
namespace WcfService1 { // 注意: 使用“重構”菜單上的“重命名”命令,可以同時更改代碼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:\\我的項目\\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(); } } }

看到有好幾位同學想要源碼的,我重新做了個測試工程,經測試只要網絡支持,是可以上傳幾十M以上的大文件的
