Solution 1

It seems that your approach of calling this web service is not correct.

You could fetch the data like this.

var request = sb.ToString();

using (var webClient = new WebClient())
{
        var response = webClient.DownloadData(request);

        var xml = Encoding.UTF8.GetString(response);

        using(var sr = new  StringReader(xml))
        {
            var dataSet = new DataSet();

            dataSet.ReadXml(sr);
        }
}

Some more info:

The DataSet itself contains 8 tables.

location,
current,
condition,
forecast,
forecastday,
day,
astro,
hour

For each of these tables you must have one DataGridView.

e.g. location can be shown like this:

dataGridView1.DataSource = dataSet.Tables[0];

private void button2_Click(object sender, EventArgs e)
{
StringBuilder sb = new StringBuilder();
sb.Append("http://api.apixu.com/v1/forecast.xml?key=5742bec32f4141e08db171907171010&q=");
sb.Append(txtcity.Text);
sb.Append("&days=");
sb.Append("7");

var request = sb.ToString();

using (var webClient = new WebClient())
{
var response = webClient.DownloadData(request);

var xml = Encoding.UTF8.GetString(response);

using (var sr = new StringReader(xml))
{
var dataSet = new DataSet();

var x = dataSet.ReadXml(sr);

dataGridView1.DataSource = x;

}
}

}
}

the result should be displayed on the dataGridView1. i wrote above but no result has been displayed please any one can fix this problem.
