C#回调转换
本文关键字:转换 回调 | 更新日期: 2023-09-27 18:25:22
我的C#比我预期的要粗糙得多,所以我一直在寻找一些帮助来启动我的项目。我尝试过许多C#到VB的转换器,但没有一个能处理SteamKit2示例中提供的回调,我所有的研究、WithEvents实验和其他尝试都失败了。如果这超出了正常stackerflow问题的范围,我很抱歉,但最重要的是,我正在寻找一个可工作的VB.net版本的C#SteamKit2示例:
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using SteamKit2;
//
// Sample 2: The Callback Manager
//
// this sample introduces the callback manager
// the callback manager is a class which can simplify the design of your program
//
// the callback manager's task is to modify the callback loop so that the handling of callbacks
// can be done in your own functions, rather than in-line with the loop
//
// in addition to the manager, your code must create an instance of a Callback<T> class
// this class routes a specific callback type to a function, and is bound only to a specific
// callback manager
//
namespace Sample2_CallbackManager
{
class Program
{
static SteamClient steamClient;
static CallbackManager manager;
static SteamUser steamUser;
static bool isRunning;
static string user, pass;
static void Main( string[] args )
{
if ( args.Length < 2 )
{
Console.WriteLine( "Sample2: No username and password specified!" );
return;
}
// save our logon details
user = args[ 0 ];
pass = args[ 1 ];
// create our steamclient instance
steamClient = new SteamClient();
// create the callback manager which will route callbacks to function calls
manager = new CallbackManager( steamClient );
// get the steamuser handler, which is used for logging on after successfully connecting
steamUser = steamClient.GetHandler<SteamUser>();
// register a few callbacks we're interested in
// these are registered upon creation to a callback manager, which will then route the callbacks
// to the functions specified
new Callback<SteamClient.ConnectedCallback>( OnConnected, manager );
new Callback<SteamClient.DisconnectedCallback>( OnDisconnected, manager );
new Callback<SteamUser.LoggedOnCallback>( OnLoggedOn, manager );
new Callback<SteamUser.LoggedOffCallback>( OnLoggedOff, manager );
isRunning = true;
Console.WriteLine( "Connecting to Steam..." );
// initiate the connection
steamClient.Connect();
// create our callback handling loop
while ( isRunning )
{
// in order for the callbacks to get routed, they need to be handled by the manager
manager.RunWaitCallbacks( TimeSpan.FromSeconds( 1 ) );
}
}
static void OnConnected( SteamClient.ConnectedCallback callback )
{
if ( callback.Result != EResult.OK )
{
Console.WriteLine( "Unable to connect to Steam: {0}", callback.Result );
isRunning = false;
return;
}
Console.WriteLine( "Connected to Steam! Logging in '{0}'...", user );
steamUser.LogOn( new SteamUser.LogOnDetails
{
Username = user,
Password = pass,
} );
}
static void OnDisconnected( SteamClient.DisconnectedCallback callback )
{
Console.WriteLine( "Disconnected from Steam" );
isRunning = false;
}
static void OnLoggedOn( SteamUser.LoggedOnCallback callback )
{
if ( callback.Result != EResult.OK )
{
if ( callback.Result == EResult.AccountLogonDenied )
{
// if we recieve AccountLogonDenied or one of it's flavors (AccountLogonDeniedNoMailSent, etc)
// then the account we're logging into is SteamGuard protected
// see sample 6 for how SteamGuard can be handled
Console.WriteLine( "Unable to logon to Steam: This account is SteamGuard protected." );
isRunning = false;
return;
}
Console.WriteLine( "Unable to logon to Steam: {0} / {1}", callback.Result, callback.ExtendedResult );
isRunning = false;
return;
}
Console.WriteLine( "Successfully logged on!" );
// at this point, we'd be able to perform actions on Steam
// for this sample we'll just log off
steamUser.LogOff();
}
static void OnLoggedOff( SteamUser.LoggedOffCallback callback )
{
Console.WriteLine( "Logged off of Steam: {0}", callback.Result );
}
}
}
new Callback<SteamClient.ConnectedCallback>( OnConnected, manager );
是我的主要障碍,但据我所知,GetHandler等早期部分虽然通过了编译,但翻译得并不好。
无论如何,任何建议(或完全转换)都将不胜感激!

对于给您带来麻烦的语句,您需要这样的东西:
Dim TempConnectedCallback As Callback(Of SteamClient.ConnectedCallback) = New Callback(Of SteamClient.ConnectedCallback)(AddressOf OnConnected, manager)
这样做的原因是VB不允许未分配给任何对象的对象实例化。
