Question

vb.net 我把access数据库放在了工程文件根目录 求相对路径

D:\My Documents\Visual Studio 2005\Projects\WindowsApplication2\WindowsApplication2这个是根目录，*.mdb就在这个下面 怎么办？

Answer 1

Private Sub Form1_Load(ByVal sender As System.Object, ByVal e As System.EventArgs) Handles MyBase.Load
OleDbConnection1.ConnectionString = "PROVIDER=Microsoft.JET.OLEDB.4.0;" & "DATA SOURCE=|DataDirectory|\数据库名.mdb"
'OleDbConnection1.ConnectionString = "PROVIDER=Microsoft.JET.OLEDB.4.0;" & "DATA SOURCE=数据库名.mdb"
OleDbDataAdapter1.Fill(DataSet11)
End Sub

数据库要放在运行文件的文件夹里
