在C#中，根據日期篩選MySQL數據庫中的數據是一個常見的操作。以下是一些基于日期的數據篩選操作函數示例：
1. 篩選特定日期的數據
public List<YourDataType> GetDataBySpecificDate(DateTime specificDate)
{List<YourDataType> dataList = new List<YourDataType>();string connectionString = "Server=myServerAddress;Database=myDatabase;Uid=myUsername;Pwd=myPassword;";using (MySqlConnection connection = new MySqlConnection(connectionString)){connection.Open();string query = "SELECT * FROM myTable WHERE DATE(date_column) = @specificDate";MySqlCommand cmd = new MySqlCommand(query, connection);cmd.Parameters.AddWithValue("@specificDate", specificDate.ToString("yyyy-MM-dd"));using (MySqlDataReader reader = cmd.ExecuteReader()){while (reader.Read()){// 讀取數據并添加到dataList中// 假設YourDataType是自定義
)
