问题描述

我需要帮助，假设我有Windows窗体包含打开的对话框和按钮，以便



uploade file to webserver （http：// localhost ：79 / uploade /）我怎么做这个







please

推荐答案

private void uploadButton_Click(object sender, EventArgs e)
{
    var openFileDialog = new OpenFileDialog();
    var dialogResult = openFileDialog.ShowDialog();
    if (dialogResult != DialogResult.OK) return;
    Upload(openFileDialog.FileName);
}

private void Upload(string fileName)
{
    var client = new WebClient();
    var uri = new Uri("http://www.yoursite.com/Uploader/");
    {
        client.Headers.Add("fileName", System.IO.Path.GetFileName(fileName));
        client.UploadFileAsync(uri, fileName);
    }
    catch (Exception ex)
    {
        MessageBox.Show(ex.Message);
    }
}

服务器：

in server:

[HttpPost]
public async Task<object> Uploader()
{
    var file = await Request.Content.ReadAsByteArrayAsync();
    var fileName =Request.Headers.GetValues("fileName").FirstOrDefault();
    var filePath = "/upload/files/";
    try
    {
        File.WriteAllBytes(HttpContext.Current.Server.MapPath(filePath) + fileName, file);
    }
    catch (Exception ex)
    {
        // ignored
    }

    return null;
}
