C# 无法使用Miniprofiler打印查询
我在我的项目中集成了实体框架和CodeFirstStoredProc库。我想记录两个库执行的查询。以前我使用的是EF提供的Database.Log委托,但由于我还想记录来自其他库的查询,所以我决定集成Miniprofiler 我使用以下代码在C# 无法使用Miniprofiler打印查询,c#,.net,mvc-mini-profiler,miniprofiler,C#,.net,Mvc Mini Profiler,Miniprofiler,我在我的项目中集成了实体框架和CodeFirstStoredProc库。我想记录两个库执行的查询。以前我使用的是EF提供的Database.Log委托,但由于我还想记录来自其他库的查询,所以我决定集成Miniprofiler 我使用以下代码在result变量中获取查询日志: MiniProfilerEF6.Initialize(); MiniProfiler.StartNew("Test"); using (MiniProfiler.Current.Step("L

变量中获取查询日志:
MiniProfilerEF6.Initialize();
MiniProfiler.StartNew("Test");
using (MiniProfiler.Current.Step("Level 1"))
{
DbConnection spConnection = new System.Data.SqlClient.SqlConnection(ConfigurationManager.ConnectionStrings["DefaultConnection"].ConnectionString);
ProfiledDbConnection profileSpConnection = new ProfiledDbConnection(spConnection, MiniProfiler.Current);
using (EfDataContext db = new EfDataContext(profileSpConnection))
{
List<Domain.PersonEntity> data = db.Persons.ToList();
}
using (StoredProcedureContext db = new StoredProcedureContext(profileSpConnection))
{
List<GetPersonResult> data = db.GetPerson.CallStoredProc(new Domain.GetPersonParameter { IsActive = true }).ToList<GetPersonResult>();
}
string result = MiniProfiler.Current.RenderPlainText();
}
MiniProfiler.Current.Stop();
我是否缺少实现方面的内容?在分析EntityFramework 6时,需要在第一次查询之前进行连接。因此,
.Initialize()
调用需要在应用程序启动时更早地进行。你可以找到
给定这些标记,看起来您处于web应用程序中,因此应该像这样提前发生:
using StackExchange.Profiling.EntityFramework6;
protected void Application_Start()
{
MiniProfilerEF6.Initialize();
}
这就是当前版本呈现自定义计时信息的方式。自定义计时是使用
CustomTiming()
而不是Step()
创建的,它们通常是MiniProfiler层次结构(如数据库交互或HTTP请求)中的叶子测量
您可以轻松自定义渲染过程并渲染有关自定义计时的详细信息:
SERVER at 23.11.2018 09:00:00
MiniProfiler = 48,3[ms]
> Foo = 35,6ms (sql = 24,8[ms] in 1 cmd) (http = 4,7[ms] in 1 cmd)
sql 24,8[ms] +16,9[ms] SELECT * FROM Foo
http 4,7[ms] +41,8[ms] GET http://foo.bar

还请注意,默认情况下,为了呈现具有所有计时的MiniProfiler报告,您需要首先调用
Stop()
。您也可以通过计算报表中到目前为止的计时来自定义此设置♦: 我正在使用控制台应用程序,我已经添加了MiniProfilerEF6.Initialize()代码>在第一行。我可能错了,但MiniProfiler的当前实现似乎没有使用实际的SQL命令文本创建自定义计时。“我用的是整洁的。”奥利维耶马特罗说,“当然应该用。”。但是您需要利用ProfiledDbConnection
decorator。请参阅MiniProfiler文档的第页。我是,但我一定是遗漏了什么,因为IDbProfiler设置为MiniProfiler.Current时,我在调用扩展方法时得到了基本结果。时间是最重要的false@OlivierMATROT没有额外的信息,就不可能说出问题所在。请提出一个包含所有细节的单独问题,我会看一看。
