检索MS Access文件中的表列表

Question

如果我可以在C#中打开与MS Access文件的连接,如何检索Access DB中存在的不同表的列表(如果可能,还可以检索与表关联的任何元数据)？

我刚从David Hayden那里找到了以下解决方案

// Microsoft Access provider factory
DbProviderFactory factory = DbProviderFactories.GetFactory("System.Data.OleDb");

DataTable userTables = null;
using (DbConnection connection = factory.CreateConnection()) {
  // c:\test\test.mdb
  connection.ConnectionString = "Provider=Microsoft.Jet.OLEDB.4.0;Data Source=c:\\test\\test.mdb";
  // We only want user tables, not system tables
  string[] restrictions = new string[4];
  restrictions[3] = "Table";

  connection.Open();

  // Get list of user tables
  userTables = connection.GetSchema("Tables", restrictions);
}

List<string> tableNames = new List<string>();
for (int i=0; i < userTables.Rows.Count; i++)
    tableNames.Add(userTables.Rows[i][2].ToString());
