error C2664: “System::Data::OleDb::OleDbConnection::OleDbConnection(System::String ^)”: 不能将参数 1 从“System::Data::OleDb::OleDbConnection ^”转换为“System::String ^”
------解决方案--------------------------------------------------------
gcnew OleDbConnection;是什么东西，是OleDbConnection 类型还string类型
------解决方案--------------------------------------------------------
本来是想用 new OleDbConnection;的，但编译不过去，提示要用gcnew。
