在C#中使用OleDB列出MS Access文件中的所有查询,可以按照以下步骤进行:
string connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\path\\to\\your\\access\\file.accdb;Persist Security Info=False;";
OleDbConnection connection = new OleDbConnection(connectionString);
connection.Open();
DataTable tables = connection.GetSchema("Tables");
foreach (DataRow row in tables.Rows)
{
string tableName = row["TABLE_NAME"].ToString();
string tableType = row["TABLE_TYPE"].ToString();
if (tableType == "VIEW")
{
Console.WriteLine("查询名称:" + tableName);
}
}
connection.Close();
完整的代码示例如下:
using System;
using System.Data.OleDb;
class Program
{
static void Main(string[] args)
{
string connectionString = "Provider=Microsoft.ACE.OLEDB.12.0;Data Source=C:\\path\\to\\your\\access\\file.accdb;Persist Security Info=False;";
OleDbConnection connection = new OleDbConnection(connectionString);
connection.Open();
DataTable tables = connection.GetSchema("Tables");
foreach (DataRow row in tables.Rows)
{
string tableName = row["TABLE_NAME"].ToString();
string tableType = row["TABLE_TYPE"].ToString();
if (tableType == "VIEW")
{
Console.WriteLine("查询名称:" + tableName);
}
}
connection.Close();
}
}
注意:在运行上述代码之前,需要安装Microsoft Access数据库引擎,并将其注册表中的相关设置进行配置。
