Creating new object of the same object multiple times, right or wrong?

int version()
{
    string versionFile = "version.xpv";
    int version;

    if (!File.Exists(versionFile))
    {
        using (StreamWriter sw = new StreamWriter(versionFile))
        {
            sw.WriteLine("0");
        }
    }

    using (StreamReader sr = new StreamReader(path))
    {
        version = Convert.ToInt32(sr.ReadLine());
        sr.Dispose();
    }

    return version;
}

int checkUpdates()
{
    int lines = 0;
    WebClient wc = new WebClient();
    using (StreamReader sr = new StreamReader(wc.OpenRead("http://127.0.0.1/patches/version.txt")))
    {
        while (sr.ReadLine() != null)
        {
            lines++;
        }
    }
    return lines;
}

string GetPatch(int version)
{
    WebClient wc = new WebClient();

    using (StreamReader sr = new StreamReader(wc.OpenRead("http://127.0.0.1/patches/version.txt")))
    {
        for (int i = 0; i < version; i++)
        {
            sr.ReadLine();
        }

        return sr.ReadLine().Substring(2);
    }
}
