c#控制台程序调试一闪而过

Question

如题，只能贴大致的代码（贴不下）：
static void Main(string[] args)
{
string a;
Console.Write("请输入所求的几何体或图形");
a = Console.ReadLine();
if (a == "矩形")
{
int a, b, s;
Console.Write("请输入矩形的长");
a = Console.Read();
Console.Write("请输入矩形的宽");
b = Console.Read();
s = shape.getarea(a, b);
Console.Write("所求矩形的面积是:");
Console.Write(s);
建的几个类
public class Geometry
{
public string name;
public int id;
}
public class shape : Geometry
{
public virtual int getarea(int a, int b)
{
int s;
s = a * b;
return s;
}
}
public class circle : shape
{
public override double getarea(int a)
{
double s;
s = 3.14 * a * a;
return s;
}
}
public class tingxing : shape
{
public override double getarea(int a, int b, int c)
{
double s;
s = (a + b) * c * 0.5;
return s;
后面放不下了，看网上说用Ctrl+f5只提示我按任意键，新人，求大神帮忙

加一个 console.readkey();
