What is the difference between Query and QueryString in asp.net

Question

Can anyone tell me what is the difference between Query and QueryString in C# or Asp.Net.

Answer 1

If you are working with ASP.NET Core, then:

• Request.QueryString: Is the raw query string. for example, in http://a.com?name=vahid&lastname=farahmandian the Request.QueryString is ?name=vahid&lastname=farahmandian which is a raw string.

• Request.Query: Is a query value collection parsed from Request.QueryString. for example in http://a.com?name=vahid&lastname=farahmandian, the Request.Query is a collection with two members:

Member 1: Key=name and Value=vahid

Member 2: Key=lastname and Value=farahmandian

Which both are parsed from Request.QueryString
