好吧，目前我正在使用Express分析器，缺点是它只适用于MS SQL Server。你可以在这里找到这个工具:https://expressprofiler.codeplex.com/

IQueryable query = from x in appEntities
                   where x.id = 32
                   select x;
var queryString = query.ToString();

将返回sql查询。使用EntityFramework的数据上下文进行工作

有两种方法:

To view the SQL that will be generated, simply call ToTraceString(). You can add it into your watch window and set a breakpoint to see what the query would be at any given point for any LINQ query. You can attach a tracer to your SQL server of choice, which will show you the final query in all its gory detail. In the case of MySQL, the easiest way to trace the queries is simply to tail the query log with tail -f. You can learn more about MySQL's logging facilities in the official documentation. For SQL Server, the easiest way is to use the included SQL Server profiler.

从EF6.1开始，您可以使用拦截器来注册数据库记录器。 请参见“拦截器”和“记录数据库操作”章节

<configuration>
  <entityFramework>
    <interceptors> 
      <interceptor type="System.Data.Entity.Infrastructure.Interception.DatabaseLogger, EntityFramework"> 
        <parameters> 
          <parameter value="C:\Temp\LogOutput.txt"/> 
          <parameter value="true" type="System.Boolean"/> 
        </parameters> 
      </interceptor> 
    </interceptors>
  </entityFramework>
</configuration>

如果您还想拥有参数值(不仅是@p_linq_0，而且还有它们的值)，您可以使用IDbCommandInterceptor并向ReaderExecuted方法添加一些日志记录。
