I write a class in C# and I want to display in console. But i can't display it.

My program doesn't have any errors, which means the program runs it but i can't see a result :(

You can use Console.WriteLine(Object)to print the output, and Console.Read()to wait for user input.
您可以使用Console.WriteLine(Object)打印输出，并使用Console.Read()等待用户输入。
Console.WriteLine("Hello world");
Console.WriteLine("Press any key to exit.");
Console.Read();
Without Console.Read, sometimes output just comes, and program exits in a flash. So Output cannot be seen/verified easily.
没有Console.Read，有时输出刚好来，程序一闪就退出。因此无法轻松查看/验证输出。

Press CTRL+F5to see your output. This will wait the console screen until you press any key.
按CTRL+F5查看您的输出。这将等待控制台屏幕，直到您按任意键。

No Problem, I get what you are asking...
没问题，我明白你的要求......
In regards to Microsoft Visual Studio 2010
关于 Microsoft Visual Studio 2010
Write
Console.WriteLine("Where are you console?");somewhere in your code - make sure you will definitely see it..Press Debug button (or the play button)
In the Microsoft Visual Studio, Go to Debug -> Windows -> Output
Console.WriteLine("Where are you console?");在您的代码中写下某处 - 确保您一定会看到它..按调试按钮（或播放按钮）
在 Microsoft Visual Studio 中，转到调试 -> Windows -> 输出
A small 'Output' Windows should pop up and you can see your console write statements! - Obviously you gotta run the code and it will appear.
应该会弹出一个小的“输出”窗口，您可以看到您的控制台写入语句！- 显然你必须运行代码，它会出现。
Hope it helps!
希望能帮助到你！

Your main structure must be in "Windows Form" architecture. So, try to attach parent (base) process, such as:
您的主要结构必须是“Windows 窗体”架构。因此，尝试附加父（基）进程，例如：
namespace MyWinFormsApp
{
static class Program
{
[DllImport("kernel32.dll")]
static extern bool AttachConsole(int dwProcessId);
private const int ATTACH_PARENT_PROCESS = -1;
[STAThread]
static void Main(string[] args)
{
if (Environment.UserInteractive) // on Console..
{
// redirect console output to parent process;
// must be before any calls to Console.WriteLine()
AttachConsole(ATTACH_PARENT_PROCESS);
// to demonstrate where the console output is going
int argCount = args == null ? 0 : args.Length;
Console.WriteLine("nYou specified {0} arguments:", argCount);
for (int i = 0; i < argCount; i++)
{
Console.WriteLine(" {0}", args[i]);
}
}
else
{
// launch the WinForms application like normal
Application.EnableVisualStyles();
Application.SetCompatibleTextRenderingDefault(false);
Application.Run(new Form1());
}
}
}
}
(or write a console app from scratch)
（或从头开始编写控制台应用程序）
