我有一个公共静态类Cashier
:
namespace MPP_TCP_Client
{
public static class Cashier
{
public static IPAddress localAddr = IPAddress.Parse("127.0.0.1");
public static TcpClient Connect()
{
try
{
return new TcpClient(Util.localAddrStr, Util.port);
}
catch (ArgumentNullException ane)
{
Console.WriteLine("ArgumentNullException: {0}", ane);
}
catch (SocketException se)
{
Console.WriteLine("SocketException: {0}", se);
}
catch (NullReferenceException nre)
{
Console.WriteLine("Null Reference Exception: {0}", nre);
}
return null;
}
// etc.
}
}
现在我想使用Connect
方法:
namespace Mpp_TCP_Client
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Press enter to start client");
Console.ReadKey();
TcpClient whatever = Cashier.Connect(); // Cashier is not being seen by Visual Studio
}
}
}
答案 0 :(得分:1)
正如上面提到的Dennis_E(我在发布此答案后注意到了他的评论):
您的命名空间有不同的外壳。
Cashier
班级使用:MPP_TCP_Client
,Program
班级使用:Mpp_TCP_Client
。
尝试匹配命名空间:
namespace MPP_TCP_Client // This should now be the same as the Cashier class
{
class Program
{
static void Main(string[] args)
{
Console.WriteLine("Press enter to start client");
Console.ReadKey();
TcpClient whatever = Cashier.Connect(); // Cashier is not being seen by Visual Studio
}
}
}
如果这是故意的,请添加以下using语句:
using MPP_TCP_Client;
