方法一

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {

            WebClient webClient = new WebClient();
            webClient.Credentials = CredentialCache.DefaultCredentials;
            try
            {
                //方法一
                FileStream fs = new FileStream(@"d:/filetxt.txt", FileMode.Open, FileAccess.Read);

                BinaryReader r = new BinaryReader(fs);

                byte[] postArray = r.ReadBytes((int)fs.Length);
                Stream postStream = webClient.OpenWrite(@"http://10.227.34.174/upload/filetxt.txt", "PUT");
                if (postStream.CanWrite)
                {
                    postStream.Write(postArray, 0, postArray.Length);
                    Console.WriteLine("Success!");
                }
                else
                {
                    Console.WriteLine("Fail!");
                }
                postStream.Close();

                ////方法二
                //webClient.UploadFile(@"http://10.227.34.174/upload/filetxt.txt", "PUT", @"d:/filetxt.txt");
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
        }
    }
}

方法二

namespace ConsoleApplication1
{
    class Program
    {
        static void Main(string[] args)
        {

            WebClient webClient = new WebClient();
            webClient.Credentials = CredentialCache.DefaultCredentials;
            try
            {
                //方法二
                webClient.UploadFile(@"http://10.227.34.174/upload/filetxt.txt", "PUT", @"d:/filetxt.txt");
            }
            catch (Exception ex)
            {
                Console.WriteLine(ex.Message);
            }
