string SelectedStr ="";
for (int i = 0; i <= this.hobby.Items.Count; i++)

if (this.hobby.Items[i].Selected == true)
{
SelectedStr += hobby.Items[i].Value + ",";
string Strhobby = "insert into stu_infor(username,hobby) values ('" + username.Text + "','" + SelectedStr + "')";
OleDbCommand myCommInsertHobby = new OleDbCommand(Strhobby, myConn);
myCommInsertHobby.ExecuteNonQuery();
}
}
其中hobby是一个CheckBoxList控件的ID号。数据库连接的代码已经写好了。今天我调试程序的时候if (this.hobby.Items[i].Selected == true)老是报错,显示索引超出范围,必须为非负值并小于集合大小,我都不知道该咋个办了,还望各位大虾多多指教哟!
