我是C#的新手,并试图从教程中运行一个示例C#程序.
当我尝试运行以下代码时,我收到以下错误:
错误1名称空间'System.Drawing'中不存在类型或命名空间名称'Point'(您是否缺少程序集引用?)C:\ Users\Documents\Visual Studio 2012\Projects\HelloWorld\HelloWorld\Class1.cs 20 28 HelloWorld
using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Threading.Tasks;
using System.Drawing;
namespace HelloWorld
{
class Hello
{
static void Main()
{
Nullable<bool> b = false;
if (b.HasValue) Console.WriteLine("b is {0}", b.Value);
else Console.WriteLine("b is not set");
System.Drawing.Point p = new System.Drawing.Point(20, 30);
Console.WriteLine(b);
Console.WriteLine("Hello World");
Console.WriteLine("Press any key to exit");
Console.ReadKey();
}
}
}
