如何使用c#.net在数据表中搜索行

using System;
using System.Data.SqlClient;

class Program
{
    static void Main()
    {
        string connectionString = "YourConnectionString";
        string searchValue = "YourSearchValue";

        using (SqlConnection connection = new SqlConnection(connectionString))
        {
            connection.Open();

            string query = "SELECT * FROM YourTable WHERE ColumnName = @SearchValue";
            SqlCommand command = new SqlCommand(query, connection);
            command.Parameters.AddWithValue("@SearchValue", searchValue);

            using (SqlDataReader reader = command.ExecuteReader())
            {
                while (reader.Read())
                {
                    // 处理每一行的数据
                    // 例如，可以读取特定列的值
                    string columnValue = reader.GetString(reader.GetOrdinal("ColumnName"));
                    Console.WriteLine(columnValue);
                }
            }
        }
    }
}
