访问 Access 2013 数据库的架构

如果我尝试读取 Access 2013 数据库的架构，我会收到以下错误：

no read permission on 'MSysRelationships'

现在帮助告诉我

User-level security features are not available in Access apps, web databases, 
or databases that use one of the new file formats (.accdb, .accde, .accdc, .accdr).

=> 我如何读取该数据库的架构？

Edit :

这是我在 Linqpad 中的代码：

var stringBuilder = new OleDbConnectionStringBuilder();
stringBuilder.Provider = "Microsoft.ACE.OLEDB.12.0";
stringBuilder.DataSource = @"C:\Recommendations.accdb";

using (var connection = new OleDbConnection(stringBuilder.ToString().Dump()))
{
    connection.Open();
    var schemaTable = connection.GetOleDbSchemaTable(OleDbSchemaGuid.Tables, new object[] {null, null, null, "TABLE"});
    var sheetName = schemaTable.AsEnumerable().Select(row => row.Field<string>("TABLE_NAME")).First();
    schemaTable.Dump();

    string  namesQuery = "SELECT DISTINCT szRelationship, szReferencedObject, szObject FROM MSysRelationships";
    string  namesQuery2 =  string.Format("select Name, Age from [{0}]", "Users");

    using (var command = new OleDbDataAdapter(namesQuery, connection))
    {
        var dataSet = new DataSet();
        command.Fill(dataSet, sheetName);
        dataSet.Dump();
    }
    connection.Close();
}

从对之前类似问题的回答来看here https://stackoverflow.com/questions/6152545/how-can-i-get-a-list-of-tables-in-an-access-jet-database，我怀疑您根本无法通过 OleDb 连接直接读取 Access 中的系统表。但是，您也许可以通过以下方式获取所需的信息：OleDbConnection.GetSchema方法（详情here http://msdn.microsoft.com/en-us/library/ms135983.aspx).
