c# - Select method in List<t> Collection -

I have an asp.net application, and now I am using a dataset for data manipulation. I have recently started converting this dataset into list archive. But, in some places it does not work. One is that in my older version I am using datarow [] drow = dataset.datatable.select (searchcriteria) . But there is no method available to find specific values ​​in the inventory collection. Is there any way of choosing some value for my search criteria? I want to know that this is possible.

Well, to get started with T & gt; There are more ways - but more idiomatic, modern approaches are to use LINQ:

  // 30 var query 1 = list is the way    Find all the old people from Person = & gt; Person.e.g. 30); // Every person's name var query2 = Search the list. Select (person => person name);  

You will need instructions to use in your file to do this work:

  using System.Linq;  

Note that they do not use wires to express future things and projects - they use a representative, usually made from lambda expressions above Are there.

If the Lambda Prices and LINQ are new to you, I suggest you first find a book covering the LINQ, such as, or your own, of course, only from the web tutorial Can learn, but I think this is an important technique, it is worth learning well to know the time.
