请教高手,C#对象数组的定义和使用.

本人刚刚学习C#,有个作业要用到对象数组.我写的有问题,希望大家帮我解决(输入姓名的时候报错:未将对象引用设置到对象的实例).  
           public  class  Student  
           {              
                       private  string  strName;  
                       double[]  dbScore=new  double[3];  
                       public  string  Name  
                       {  
                                   set  
                                   {  
                                               strName=value;  
                                   }  
                                   get  
                                   {  
                                               return  strName;  
                                   }  
                       }                          
 
                       public  double  this[int  nIndex]//索引器  
                       {  
                                   get  
                                   {  
                                               return  dbScore[nIndex];  
                                   }  
                                   set  
                                   {  
                                               dbScore[nIndex]=value;  
                                   }  
                       }  
 
                         
           }  
                   class  Class1  
           {  
                       ///  

  
                       ///  应用程序的主入口点。  
                       ///  

  
                       [STAThread]  
                       static  void  Main(string[]  args)  
                       {  
                                   //  
                                   //  TODO:  在此处添加代码以启动应用程序  
                                   //  
                                   Student[]  stuPer=new  Student[1];///对象数组  
                         
                                   Console.WriteLine("输入姓名:");  
 
                                   stuPer[0].Name=Console.ReadLine();  
                                   Console.WriteLine("姓名是:{0}",stuPer[0].Name);
