如何在ExecuteReader c#中更改小数分隔符

CultureInfo newCulture = new CultureInfo(CultureInfo.CurrentCulture.Name);
newCulture.NumberFormat.NumberDecimalSeparator = ",";

Thread.CurrentThread.CurrentCulture = newCulture;

using System;
using System.Data.SqlClient;
using System.Globalization;
using System.Threading;

class Program
{
    static void Main()
    {
        // 创建新的区域设置对象并更改小数分隔符
        CultureInfo newCulture = new CultureInfo(CultureInfo.CurrentCulture.Name);
        newCulture.NumberFormat.NumberDecimalSeparator = ",";
        Thread.CurrentThread.CurrentCulture = newCulture;

        // 执行数据库查询
        string connectionString = "your_connection_string";
        string query = "SELECT * FROM your_table";
        using (SqlConnection connection = new SqlConnection(connectionString))
        {
            connection.Open();
            SqlCommand command = new SqlCommand(query, connection);
            SqlDataReader reader = command.ExecuteReader();

            // 处理查询结果
            while (reader.Read())
            {
                // 读取数据行中的小数值
                decimal decimalValue = reader.GetDecimal(0);
                Console.WriteLine(decimalValue);
            }

            reader.Close();
        }
    }
}
