[英]C# call method from different class with 'args' as a parameter
我正在寫一個 Discord Bot (Discord.net),我發現自己需要使用他們的API訪問谷歌表上的一些數據。 因為我認為最好將這兩個實際分開在兩個不同的 class 文件中,我嘗試將 Google API 的Main方法調用到我的程序中(在將其重命名為“ Sheets ”之后),就像在我的Program.cs中這樣:
using Discord;
using Discord.WebSocket;
using System;
using System.IO;
using System.Threading.Tasks;
namespace WoM_Balance_Bot
{
public class Program
{
public static void Main(string[] args)
{
GoogleAPI GSheet = new GoogleAPI();
GSheet.Sheets();
new Program().MainAsync().GetAwaiter().GetResult();
}
private DiscordSocketClient _client;
public async Task MainAsync()
{
_client = new DiscordSocketClient();
_client.MessageReceived += CommandHandler;
_client.Log += Log;
var token = File.ReadAllText("bot-token.txt");
await _client.LoginAsync(TokenType.Bot, token);
await _client.StartAsync();
// Block this task until the program is closed.
await Task.Delay(-1);
}.......ecc
我嘗試編寫要在這些括號中傳遞的參數,例如“ string ”和“ args ”,但要么我的語法錯誤,要么我對確切傳遞的內容有一個非常錯誤的想法。
這是GoogleAPI.cs的實際內容,這是我創建的另一個 class 文件,它具有 Google Sheet API:
using Google.Apis.Auth.OAuth2;
using Google.Apis.Services;
using Google.Apis.Sheets.v4;
using Google.Apis.Sheets.v4.Data;
using Google.Apis.Util.Store;
using System;
using System.Collections.Generic;
using System.IO;
using System.Threading;
namespace WoM_Balance_Bot
{
public class GoogleAPI
{
// If modifying these scopes, delete your previously saved credentials
// at ~/.credentials/sheets.googleapis.com-dotnet-quickstart.json
private static readonly string[] Scopes = { SheetsService.Scope.SpreadsheetsReadonly };
private static readonly string ApplicationName = "wombankrolls";
public static void Sheets(string[] args)
{
UserCredential credential;
Console.WriteLine("if you read this then it's good");
using (var stream =
new FileStream("credentials.json", FileMode.Open, FileAccess.Read))
{
// The file token.json stores the user's access and refresh tokens, and is created
// automatically when the authorization flow completes for the first time.
string credPath = "token.json";
credential = GoogleWebAuthorizationBroker.AuthorizeAsync(
GoogleClientSecrets.Load(stream).Secrets,
Scopes,
"user",
CancellationToken.None,
new FileDataStore(credPath, true)).Result;
Console.WriteLine("Credential file saved to: " + credPath);
}
// Create Google Sheets API service.
var service = new SheetsService(new BaseClientService.Initializer()
{
HttpClientInitializer = credential,
ApplicationName = ApplicationName,
});
// Define request parameters.
String spreadsheetId = "16W56LWqt6wDaYAU5xNdTWCdaY_gkuQyl4CE1lPpUui4";
String range = "Class Data!G163:I";
SpreadsheetsResource.ValuesResource.GetRequest request =
service.Spreadsheets.Values.Get(spreadsheetId, range);
// Prints the names and majors of students in a sample spreadsheet:
// https://docs.google.com/spreadsheets/d/1BxiMVs0XRA5nFMdKvBdBZjgmUUqptlbs74OgvE2upms/edit
ValueRange response = request.Execute();
IList<IList<Object>> values = response.Values;
/*
if (values != null && values.Count > 0)
{
Console.WriteLine("Name, Major");
foreach (var row in values)
{
// Print columns A and E, which correspond to indices 0 and 4.
Console.WriteLine("{0}, {1}", row[0], row[4]);
}
}
else
{
Console.WriteLine("No data found.");
}
Console.Read();
*/
}
}
}
我已經從谷歌給出的快速入門中修改了它,我認為它是有道理的,但最終我仍然得到同樣的錯誤:
沒有給出與“GoogleAPI.Sheets(string[])”的所需形式參數“args”相對應的參數
正如用戶“ David L ”在評論中所寫:作為一般經驗法則,如果您不使用參數,請將其刪除。 C# 如果您的方法需要一個參數並且您沒有提供一個參數,則通過引發編譯器錯誤來幫助強制執行此范例,這正是這里發生的情況。
這是我的錯,因為在 API 實施期間,我的印象完全相反。 因此,我希望始終以干凈的代碼為目標,而保留我不會使用的東西是我的壞事。 謝謝大衛!
