Answer 1

我的webmethod是这样的:
[WebMethod]
    public bool SendFileBinary(string fileFullPath, byte[] binaryArray)
    {
        try
        {
            FileStream fs;
            fs = new FileStream(Server.MapPath(@"./" + UploadPath + "/" + fileFullPath), FileMode.OpenOrCreate, FileAccess.Write, FileShare.Write, binaryArray.Length, false);
            if (fs.CanWrite && fs.CanSeek)
            {
                fs.Seek(fs.Length, SeekOrigin.Begin);
                fs.Write(binaryArray, 0, binaryArray.Length);
                fs.Close();
                fs.Dispose();
                return true;
            }
            else
            {
                return false;
            }
        }
        catch
        {
            return false;
        }
    }
