我很菜啊，编译下面代码时出错了，帮忙看看啊！
先谢谢了！

using System; // Namespace Declaration
class OutputClass // helper class
{
string myString;
public OutputClass(string inputString) // Constructor构造器
{
myString = inputString;
}
public void printString() // Instance实例 Method
{
Console.WriteLine("{0}", myString);
}
~OutputClass() // Destructor
{
} // Some resource cleanup routines
}

class ExampleClass // Program start class
{
public static void Main() // Main begins program execution.
{
OutputClass outCl = new OutputClass("This is printed by the output class.") {} // Instance of OutputClass
outCl.printString(); // Call Output class' method
}
}

错误提示是：classes.cs(22,80): error CS1002: ; expected

应该怎么调整一下啊，我把OutputClass outCl = new OutputClass("This is printed by the output class.") {}  后面这俩花括号去掉了就能够正常输出了！
