how to convert a string with linq query content

TataReddy_CTS

Hi, I want to convert a “string” to its equivalent LINQ expression. Can someone pls help me with this? Like: String s= “from c in context.CpSoftwareResourceMaster select c”; to its equivalent linq expression. Its return type will be IQueriable<CpSoftwareResourceMasterEntity> actual here the string may even change dynamically. I mean at run time.. Ny Idea??

I think you are confused with the code.Your question is not clear. vat u mean by,

This is more complicated than you may think. Basically, I think you are going to have to create dummy code that you compile at runtime (after injecting this string) and execute in a separate application domain. This isn't going to be pretty.

I'm not sure what your usage is for something like this but it seems to be in the same category as inline SQL statements, something that should not be used. If your intention is to allow users to form dynamic queries then I would question why you would give them access to the data model in such a manner and do they really need to know, or understand, the objects and how to write queries. If you are not exposing it to users, then why do this; you should know your model and not need to form dynamic queries. You can create a library queries to be executed later as needed.

I guess the only way to execute a dynamic linq-statement at all is to generate a dynamic code at runtime and use the statement as only dynamic part. for more information i found this page for example i've just googled for that hope this helps!
