yeah it seems u have 2 files that define 2 classes of Program and 2 main methods
delete one of the files
usually a file that ends with .designer.cs should be only for designing forms, not for main methods
Why do you have a
HttpClient if you're not using it?
WebRequest is not recommendedCurrently CS0017 error is appearing.

namespace ConsoleApp1
{
class Program
{
static HttpClient client = new HttpClient();
public static HttpClient Client { get => Client1; set => Client1 = value; }
public static HttpClient Client1 { get => Client3; set => Client3 = value; }
public static HttpClient Client2 { get => Client3; set => Client3 = value; }
public static HttpClient Client3 { get => client; set => client = value; }
static void Main(string[] args)
{
string url = "http://apis.data.go.kr/1360000/EqkInfoService/getEqkMsg"; // URL
url += "?ServiceKey=" + "[API KEY}"; // Service Key
url += "&pageNo=1";
url += "&numOfRows=10";
url += "&dataType=XML";
url += "&fromTmFc=20171101";
url += "&toTmFc=20171129";
var request = (HttpWebRequest)WebRequest.Create(url);
request.Method = "GET";
string results = string.Empty;
HttpWebResponse response;
using (response = request.GetResponse() as HttpWebResponse)
{
StreamReader reader = new StreamReader(response.GetResponseStream());
results = reader.ReadToEnd();
}
Console.WriteLine(results);
}
}
}
Means you have more than one main method
Is there any other file you have in the project?
Umm
There is a file
Does it have a
Main method inside?
Or, on the contrary, no methods or classes, just top-level code?Hmm, it looks like I put the same code in different files.
:pepeCEASE:
But which file should I put that code in?:bigthonk:
You can have only one, single, main file
You can spread the code across however many other files you want, yes
But there can only be one entry point
The error has been resolved. Thank you to everyone who helped.
