晕了晕了 几句话都出错。好久没做了数据库大家帮看下
public DB() {
strCon = @"Provider = Microsoft.Jet.OLEDB.4.0 ; Data Source = f:\tool\package\anforma_AU\pack_tool_zerogra_1.00_自动版\pack_tool\bin\Debug\config\database\database\AU_DB.mdb";
}

public void getDB() {
try {
if (sqlCon==null)
sqlCon = new OleDbConnection(strCon);
if (sqlCon.State != ConnectionState.Open)
sqlCon.Open(); /////////打开这个始终出错
ds = new DataSet();
string strCom = "select * from auTable";
sqlDA = new OleDbDataAdapter(strCom, sqlCon);
sqlDA.Fill(ds, "auTable");

sqlCon.Close();

BusinessEntity.DataSet = ds;
}
catch { }
}

连接access需要配置什么吗，难道我没配置？

[解决办法]

C# code

strCon = @"Provider = Microsoft.Jet.OLEDB.4.0 ; Data Source = f:\tool\package\anforma_AU\pack_tool_zerogra_1.00_自动版\pack_tool\bin \Debug\config\database\database\AU_DB.mdb";  sqlCon = new OleDbConnection(strCon);
