c# – 使用OLEDB从Stream读取AccessFile到DataSet

public void GetAccessDB(string filepath){

this.ConnectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source = " + filepath;
// get Table Names
this.TableNames = new List<string>();
using (System.Data.OleDb.OleDbConnection oledbConnection = new System.Data.OleDb.OleDbConnection(this.ConnectionString))
{
oledbConnection.Open();
System.Data.DataTable dt = null;
dt = oledbConnection.GetOleDbSchemaTable(System.Data.OleDb.OleDbSchemaGuid.Tables,null);
foreach (System.Data.DataRow row in dt.Rows)
{
  string strSheetTableName = row["TABLE_NAME"].ToString();
  if (row["TABLE_TYPE"].ToString() == "TABLE")
     this.TableNames.Add(strSheetTableName);
}
oledbConnection.Close();
}


this.Dataset = new System.Data.DataSet();
using (System.Data.OleDb.OleDbConnection oledbConnection = new System.Data.OleDb.OleDbConnection(this.ConnectionString))
{
  foreach (string table in this.TableNames)
  {
    string command = string.Format("SELECT * FROM {0};",table);
    using (System.Data.OleDb.OleDbCommand cmd = new System.Data.OleDb.OleDbCommand(command,oledbConnection))
    {
      cmd.CommandType = System.Data.CommandType.Text;
      oledbConnection.Open();
      System.Data.OleDb.OleDbDataReader dr = cmd.ExecuteReader();
      this.Dataset.Load(dr,System.Data.LoadOption.OverwriteChanges,table);
      oledbConnection.Close();
    }
  }
}
}

但是我需要从Stream获取Access文件,而且我暂时不能将它写在磁盘上,那你的建议是什么？

我需要GetAccessDB的这个重载(Stream AccessFile)？
我搜索并找到This,但这对我来说并不清楚,我最终需要通过Access File中的所有表获取DataSet.

有人知道吗？
