如何在Microsoft BOT Framework4中从数据库中获取数据

using System.Data.SqlClient;

// 连接数据库
string connectionString = "YourConnectionString";
using (SqlConnection connection = new SqlConnection(connectionString))
{
    connection.Open();

    // 编写查询语句
    string query = "SELECT * FROM YourTable";

    // 执行查询
    using (SqlCommand command = new SqlCommand(query, connection))
    {
        // 处理结果
        using (SqlDataReader reader = command.ExecuteReader())
        {
            while (reader.Read())
            {
                // 读取数据并进行处理
                string data = reader.GetString(0);
                // ...
            }
        }
    }
}
