LINQPad, using multiple datacontexts

由 偶尔善良 提交于 2019-11-27 05:16:31
问题 I am often comparing data in tables in different databases. These databases do not have the same schema. In TSQL, I can reference them with the DB>user>table structure ( DB1.dbo.Stores , DB2.dbo.OtherPlaces ) to pull the data for comparison. I like the idea of LINQPad quite a bit, but I just can't seem to easily pull data from two different data contexts within the same set of statements. I've seen people suggest simply changing the connection string to pull the data from the other source

How do I use the LINQPad Dump() extension method in Visual Studio? [closed]

LINQPad is amazing, and particularly useful is the Dump() extension methods which renders objects and structs of almost any type, anonymous or not, to the console. Initially, when I moved to Visual Studio 2010, I tried to make my own Dump method using a delegate to get the values to render for anonymous types, etc. It's getting pretty complicated though and while it was fun and educational at first, I need a solid implementation. Having checked out the LINQPad code in .NET Reflector I am even more assured that I'm not going to get the implementation right. Is there a free library I can include

问题 Does anyone have a complete list of LINQPad extension methods and methods, such as .Dump() SubmitChanges() 回答1: LINQPad defines two extension methods (in LINQPad.Extensions), namely Dump() and Disassemble() . Dump() writes to the output window using LINQPad's output formatter and is overloaded to let you specify a heading: typeof (int).Assembly.Dump (); typeof (int).Assembly.Dump ("mscorlib"); You can also specify a maximum recursion depth to override the default of 5 levels: typeof (int)
