数据库SqlDataReader的读取问题！

[xiaocui2007]

string myConnectionString = "Initial Catalog=S_T;Data Source=localhost;Integrated Security=SSPI";
SqlConnection myCon = new SqlConnection(myConnectionString);
string mySelectquery = "select Sno,Sname from Student";
SqlCommand myCommand = new SqlCommand(mySelectquery,myCon);
myCon.Open(); //打开连接
SqlDataReader myReader;
myReader = myCommand.ExecuteReader();

while(myReader.Read())
{
myReader.GetInt32(0) + "," + myReader.GetString(1); //本行有错误
}
myReader.Close();
myCon.Close();
------------------------------------
错误提示
只有 assignment、call、increment、decrement 和 new 对象表达式可用作语句

这是什么原因啊？在网上没有找到答案！

错误提示的意思是说：
只有赋值，函数调用，++,--，new操作可以当成一个语句。

[wuyq11]

string s= myReader.GetString(1);

[wiki14]

myReader.GetInt32(0);
myReader.GetString(1);  

[满衣兄]

string str = myReader.GetInt32(0) + "," + myReader.GetString(1); //本行有错误

关注中

[koukoujiayi]

string str = myReader.GetInt32(0).ToString() + "," + myReader.GetString(1).ToString(); //本行这样没错误

[waiwai1015]

string str = myReader.GetInt32(0).ToString() + "," + myReader.GetString(1).ToString();
