VS2010A使用chart控件读取数据库，如何只读取指定位数数据

case 'F':printf("friday\n")break

case 'M':printf("monday\n")break

case 'T':printf("please input second letter\n")

if((letter=getch())=='u')

printf("tuesday\n")

else if ((letter=getch())=='h')

printf("thursday\n")

else printf("data error\n")

先读取数据库的路径，用select *form base；得到路径之后，

//StreamReader objReader = new StreamReader(@"C:\Users\loa\Desktop\test.txt")

//string sLine = ""

//ArrayList arrText = new ArrayList()

//while (sLine != null)

//{

//sLine = objReader.ReadLine()

//if (sLine != null)

//arrText.Add(sLine)

//}

//objReader.Close()

//foreach (string sOutput in arrText)

//Console.WriteLine(sOutput)
