winform采用POST上传指定文件，并获取返回值
Web端代码
1 public partial class transform : System.Web.UI.Page
2 {
3 string path = "E:\\test\\uploadfi";
4 protected void Page_Load(object sender, EventArgs e)
5 {
6
7 if (!string.IsNullOrEmpty(Request["fileName"]))
8 {
9 Response.Write(UploadFileWithString(Request["fileName"], Request.InputStream));
10 //Response输出返回值
11
12 }
13 }
14
15
16 protected string UploadFileWithString(string fileName,Stream streams)
17 {
18
19 byte[] b = new byte[Convert.ToInt32( streams.Length)];
20 streams.Read(b, 0, Convert.ToInt32(streams.Length));
21
22 string creatpath = path + "\\sh";
23 MemoryStream ms = new MemoryStream(b);
24 if (!Directory.Exists(creatpath))
25 Directory.CreateDirectory(creatpath);
26 try
27 {
28 FileStream fs = new FileStream(creatpath + "\\" + fileName, FileMode.Create);
29 ms.WriteTo(fs);
30 ms.Close();
31 fs.Close();
32 return "1";
33 }
34 catch
35 {
36 return "0";
37 }
38 }
winform端代码
1 private void button2_Click(object sender, EventArgs e)
2 {
3
4 if (openFileDialog1.ShowDialog() == DialogResult.OK)
5 label2.Text = openFileDialog1.FileName;
6 FileInfo f = new FileInfo(openFileDialog1.FileName);
7 WebUpload(openFileDialog1.SafeFileName, f);
8
9 }
10 protected void WebUpload(string fileName, FileInfo f)
11 {
12 WebClient webc = new WebClient();
13 FileStream fs = new FileStream(f.FullName, FileMode.Open, FileAccess.Read);
14 byte[] byteString=new byte[f.Length];
15 fs.Read(byteString, 0,Convert.ToInt32(f.Length));
16 fs.Close();
17
18 byte[] returnVal = webc.UploadData("http://localhost/sz/transform.aspx?fileName="+HttpUtility.UrlEncode(fileName,Encoding.GetEncoding("gb2312")), "post",byteString);
19
20 MessageBox.Show(Encoding.GetEncoding("gb2312").GetString(returnVal));//返回值
