Solution 1

I see at least 3 things wrong:

You've exposed your APIXU private key to the world by including it in your post.
The 2nd .Append() call should be .Append("&days=7").
You don't need the last .Append() call.

The URL http://api.apixu.com/v1/forecast.xml?key=[KEY]&q=Paris&days=7 returns 7 days for me.

Solution 2

You are using a placeholder while building your string, but you may use it incorrectly.
Maybe try:

C#

int numberOfDays = 7;
StringBuilder sb = new StringBuilder();
sb.Append("http://api.apixu.com/v1/forecast.xml?key=<redacted>&q=");
sb.Append(txtcity.Text);
sb.AppendFormat("&days={0}", numberOfDays);

Depending on C# version you are using, you may also try:

C#

sb.Append($"&days={numberOfDays}");

(notice the $ sign in front of the string in the second version).
You could also group this into a single statement, eliminating the need to create a new StringBuilder everytime the method is called:

C#

string key = "<redacted>";
string city = txtcity.Text;
int numberOfDays = 7;
string requestText = $"http://api.apixu.com/v1/forecast.xml?key={key}&q={city}&days={numberOfDays}";

Finally, there seems to be a C# specific API that you could try to use:
apixu/apixu-csharp
[^]
Hope this helps. Kindly.

Sorry, CodeProject is not a code-ordering service. I'm OK to help when there are some difficulties, but I will never do your work for you.
Since you seem to have a valid subscription to this service, I suggest you seek support from them. I personnaly never have used apixu service, nor do I plan to, at least in nearby future.

string uri = string.Format("http://api.apixu.com/v1/forecast.xml?key=5742bec32f4141e08db171907171010&q={0}&days=7", city);
XDocument doc = XDocument.Load(uri);
foreach (var npc in doc.Descendants("forecastday"))
{
MessageBox.Show((string)npc.Descendants("date").FirstOrDefault());
MessageBox.Show("Max temp " + (string)npc.Descendants("maxtemp_c").FirstOrDefault());
MessageBox.Show("Min temp " + (string)npc.Descendants("mintemp_c").FirstOrDefault());
MessageBox.Show("Text " + (string)npc.Descendants("text").FirstOrDefault());
MessageBox.Show("Icon " + (string)npc.Descendants("http"+"icon").FirstOrDefault());

}
now working successfully. instead of message box how can put all data in to the data grid
