SqlBulkCopy在Visual C++中出现内存泄漏

[weixin_38059951]

SqlBulkCopy在Visual C++里面怎么用，我参照C#代码http://www.cnblogs.com/muliang/p/3831797.html写的visual C++程序，发现使用SqlBulkCopy出现内存泄漏，主要代码如下：SqlConnection^ Conn = gcnew SqlConnection();SqlConnection^ Conn->ConnectionString = Marshal::PtrToStringAnsi((IntPtr)cSQLCmd);SqlConnection^ Conn->Open();DataTable^   Table = gcnew DataTable();DataRow^     Row;SqlBulkCopy^ BulkCopy = gcnew SqlBulkCopy(Conn);Table->Columns->Add("nMachID", System::Type::GetType("System.String"));Table->Columns->Add("lSampTime", System::Type::GetType("System.String"));Row = Table->NewRow();Row["nMachID"] = Marshal::PtrToStringAnsi((IntPtr)cDeviceName);Row["lSampTime"] = Marshal::PtrToStringAnsi((IntPtr)cSampTime);Table->Rows->Add(Row);BulkCopy->DestinationTableName = Marshal::PtrToStringAnsi((IntPtr)cDataSheetName);BulkCopy->ColumnMappings->Add("nMachID", "nMachID");//前者为临时表，后者为目标表BulkCopy->ColumnMappings->Add("lSampTime", "lSampTime");BulkCopy->WriteToServer(Table);BulkCopy->Close();Table->Rows->Clear();请高手看下，如何解决。万分感谢。
