Compiler Warning: No data for encoding 1252

[chozokennedy]

Hello, I'm currently using windows 8 64-bit OS and C# in Visual Studio 2010 64bit. I'm getting some warning when compiling. How can I fix this warning ?

My Codes ( C#) :

using System;
using System.Collections.Generic;
using System.ComponentModel;
using System.Data;
using System.Drawing;
using System.Linq;
using System.Text;
using System.Windows.Forms;
using System.Net;

namespace SkillFeed_Downloader
{
    public partial class Form1 : Form
    {
        public Form1()
        {
            InitializeComponent();
        }

        private void btnfiledialog_Click(object sender, EventArgs e)
        {
            OpenFileDialog fd = new OpenFileDialog();
            fd.ShowDialog();
            filepath.Text = fd.FileName;
            filepath.Enabled = false;

        }

        private void btndownload_Click(object sender, EventArgs e)
        {
            WebClient client = new WebClient();
            client.Encoding = System.Text.Encoding.UTF8;
            string url = txturl.Text;
            string path = filepath.Text;
            client.DownloadFileAsync(new Uri(url), (path));
            client.DownloadProgressChanged += new DownloadProgressChangedEventHandler(client_DownloadProgressChanged);

        }

        void client_DownloadProgressChanged(object sender, DownloadProgressChangedEventArgs e)
        {
            progressBar1.Value = e.ProgressPercentage;
            lblbytereceived.Text = e.BytesReceived.ToString();
            lbltotalbytes.Text = e.TotalBytesToReceive.ToString();
        }

        private void Form1_Load(object sender, EventArgs e)
        {
          
        }
    }
}
