If it's in a desktop application, you just need

_context.Log = Console.Out;

Linq To SQL output SQL statements. But what about ASP.NET? Then I remembered StringWriter. Instead of Console.Out, it can help us receive the output logs and save them in a StringBuilder.

So construct an auxiliary class:

using System; using System.Collections.Generic; using System.Linq; using System.Web; using System.IO; using System.Text; namespace Clowwindy.Models { public static class LogHelper { public static StringBuilder Log = new StringBuilder(); public static TextWriter In = new StringWriter(Log); public static string GetAllLog() { In.Flush(); return Log.ToString();} public static void Clean() { Log = new StringBuilder(); In = new StringWriter(Log); } } } About "Linq To SQL how to output SQL statements" This article is shared here, I hope the above content can have some help for everyone, so that you can learn more knowledge, if you think the article is good, please share it for more people to see.
