如何在C#中调用SQL函数？

using System.Data.SqlClient;

string connectionString = "Data Source=myServerAddress;Initial Catalog=myDatabase;User Id=myUsername;Password=myPassword;";
string query = "SELECT * FROM dbo.MyFunction(@param1, @param2)";

using (SqlConnection connection = new SqlConnection(connectionString))
{
    SqlCommand command = new SqlCommand(query, connection);
    command.Parameters.AddWithValue("@param1", "value1");
    command.Parameters.AddWithValue("@param2", "value2");

    connection.Open();

    using (SqlDataReader reader = command.ExecuteReader())
    {
        while (reader.Read())
        {
            // 处理结果集
        }
    }
}

public class MyDbContext : DbContext
{
    public DbSet<MyFunctionResult> MyFunctionResults { get; set; }

    // ...其他代码
}

using (var context = new MyDbContext())
{
    var results = context.MyFunctionResults
        .FromSqlRaw("SELECT * FROM dbo.MyFunction(@param1, @param2)", "value1", "value2")
        .ToList();
}
