OleDbDataReader以ArrayList在C＃

Question

如何迭代通過OleDbDataReader並將其元素放入ArrayList？

這裏是我的代碼：

// ... 

ArrayList list = new ArrayList(); 

while(myReader.Read()) 
{ 
    foreach(string s in myReader) // I got an Exception here 
    { 
     list.Add(s); 
    } 
} 

// ... 

Label lbl = new Label(); 
lbl.Text = list[i] as string; 

這裏是例外：

System.InvalidCastException: Unable to cast object of type 'System.Data.Common.DataRecordInternal' to type 'System.String'. 

Answer 1

試試這個：

while (myReader.Read()) 
{ 
    list.Add(myReader.GetString(0)); 
}
