这是我的代码。C#命名空间'System.Windows'中不存在类型或命名空间名称'Forms'
namespace TextRPG1
{
public class Program
{
private bool nonyn = false;
static void Main(string[] args)
{
//Introduction
Console.WriteLine("Welcome to TextRPG By AgentMcBride.");
Console.WriteLine("You can exit at any time by hitting the ESC key!");
Console.WriteLine("Press any key to begin!");
Console.ReadKey();
Console.WriteLine("Great! Lets begin!");
//Backstory
Console.WriteLine(" BACKSTORY: You are a peasant trying to work his way through the castle to save the princess.");
//Inventory tutorial
Console.WriteLine("INVENTORY: You will pick up items along the way to help you save the princess. When encountering an item, the program will ask you y or n. Type y to collect the item. Note: You can only store 5 items at a time in your sack!");
Console.WriteLine("Lets try picking up an item!");
Console.WriteLine("You have found an apple! Would you like to put it in your sack? Type y or n!");
//Handle the KeyDown event to determine the type of character entered into the control.
private void textBox1_KeyDown(object sender, System.Windows.Forms.KeyEventArgs e)
{
// Initialize the flag to false.
nonyn = false;
// Determine whether the keystroke is a number from the top of the keyboard.
if (e.KeyCode < Keys.D0 || e.KeyCode > Keys.D9)
{
// Determine whether the keystroke is a number from the keypad.
if (e.KeyCode < Keys.NumPad0 || e.KeyCode > Keys.NumPad9)
{
// Determine whether the keystroke is a backspace.
if(e.KeyCode != Keys.Back)
{
// A non-numerical keystroke was pressed.
// Set the flag to true and evaluate in KeyPress event.
nonyn = true;
}
}
}
//If shift key was pressed, it's not a number.
if (Control.ModifierKeys == Keys.Shift)
{
nonyn = true;
}
}
// This event occurs after the KeyDown event and can be used to prevent
// characters from entering the control.
private void textBox1_KeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
// Check for the flag being set in the KeyDown event.
if (nonyn == true)
{
// Stop the character from being entered into the control since it is non-numerical.
e.Handled = true;
}
}
}
}
}
它不断给我的错误
“的类型或命名空间名称‘形式’并不在命名空间存在‘System.Windows’”
在那里说System.Windows.Forms的.KeyEventArgs
此外,在当前上下文中找不到名称“key”和“control”。

'命名空间'System.Windows'中不存在类型或命名空间名称'Forms' - 这是正确的。 'Forms'类存在于'System.Windows.Forms'中。 – Brian
