来自不同 class 的 C# 调用方法,使用 'args' 作为参数
C# call method from different class with 'args' as a parameter
我正在编写一个 Discord Bot (Discord.net),我发现自己需要使用他们的 API 访问 google sheet 上的一些数据。因为我认为最好将这两个文件分开放在两个不同的 class 文件中,我尝试将 Google API 的 Main 方法调用到我的程序中(重命名后“Sheets”)就像我的Program.cs:
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
我尝试编写要传递到此处的参数 in these parentheses,例如“string”和“args" 但是要么我的语法错误,要么我对要传递的内容有一个非常错误的想法。
这是 GoogleAPI.cs 的实际内容,这是我创建的另一个 class 文件,其中包含 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();
*/
}
}
}
我已经根据 Google 给出的 quickstart 以我认为合理的方式对其进行了修改,但最终我仍然遇到相同的错误:
There is no argument given that corresponds to the required formal parameter 'args' of 'GoogleAPI.Sheets(string[])'
作为用户“David L”在评论中写道:
根据一般经验,如果您不使用参数,请将其删除。如果您的方法需要一个参数而您没有提供参数,C# 会通过抛出编译器错误来帮助强制执行此范例,这正是此处发生的情况。
这是我的错,因为在 API 实施期间我的印象完全相反。因此,我想始终以干净的代码为目标,保留我不会使用的东西是我的错。谢谢大卫!
