不解的错误：An unhandled exception of type 'System.Data.OleDb.OleDbException' occurred in system.data.dll

[puppeteer]

OleDbConnection myConnection = new OleDbConnection("Provider=Microsoft.Jet.OLEDB.4.0;Data Source=TYPDB.mdb");

myConnection.Open();

OleDbCommand myCommand = new OleDbCommand();
OleDbTransaction myTrans;

myTrans = myConnection.BeginTransaction();
myCommand.Connection = myConnection;
myCommand.Transaction = myTrans;

在此处报错：OleDbCommand myCommand = new OleDbCommand();

不明！

哪个能帮我解决一下？

occurred in system.data.dll这个错误什么意思？
