- C# Linq Method Syntax
Many of the methods you'd typically use in the Convert class can be converted to corresponding sql function calls. So you would use `Convert.ToInt32` or other conversion functions. You can also map out the sql functions that you want to use in your query that are not directly supported. LINQ utility functions like IndexOf, ForEach, ItemAt that should have been included in LINQ - LinqUtil.cs. Public static System.Linq.Expressions.UnaryExpression Convert (System.Linq.Expressions.Expression expression, Type type); The following code example shows how to create an expression that represents a type conversion operation. // Add the following directive to your file: // using System.Linq. For more information, see Type Relationships in LINQ Query Operations. Letting the Compiler Handle Generic Type Declarations. If you prefer, you can avoid generic syntax by using the var keyword. The var keyword instructs the compiler to infer the type of a query variable by looking at the data source specified in the from clause.
Convert.NET is a free (for-personal-use) portable text conversion and processing toolkit, aimed at developers but useful for others, too.

A translation module acts as a shell for multiple translation engines (Google, Bing, Yandex, Excite), and supports 94 languages. It's able to check text in a text box (something you've typed or copied from the clipboard), at a URL, in one or more local or remote documents.
There's a full-strength C# <> VB.NET converter, also with support for converting anything from a pasted chunk of code to multiple files.
An Encrypt/ Decrypt module allows you to create encoded text messages using AES, Rijndael, DES, TripleDES or SHA.
An Encoding/ Decoding module converts text and files between various encoding schemes (Base64/ HTML/ URL/ URL-js/ ESCAPE-js).
There's also a LINQ tester, a regular expression tester, and - just in case you needed one - an HTML/ JSON/ XML browser thrown in as well.

Convert.NET has a bizarre mix of features, but the translator will be worth having for most people, and the C# <> VB.NET converter is a plus for developers.-->
LINQ queries are based on generic types, which were introduced in version 2.0 of .NET Framework. You do not need an in-depth knowledge of generics before you can start writing queries. However, you may want to understand two basic concepts:

When you create an instance of a generic collection class such as List<T>, you replace the 'T' with the type of objects that the list will hold. For example, a list of strings is expressed as
List<string>, and a list of
Customerobjects is expressed as
List<Customer>. A generic list is strongly typed and provides many benefits over collections that store their elements as Object. If you try to add a
List<string>, you will get an error at compile time. It is easy to use generic collections because you do not have to perform run-time type-casting.
IEnumerable<T> is the interface that enables generic collection classes to be enumerated by using the
foreachstatement. Generic collection classes support IEnumerable<T> just as non-generic collection classes such as ArrayList support IEnumerable.
For more information about generics, see Generics.
IEnumerable<T> variables in LINQ Queries
LINQ query variables are typed as IEnumerable<T> or a derived type such as IQueryable<T>. When you see a query variable that is typed as
IEnumerable<Customer>, it just means that the query, when it is executed, will produce a sequence of zero or more

Letting the Compiler Handle Generic Type Declarations

If you prefer, you can avoid generic syntax by using the var keyword. The
var keyword instructs the compiler to infer the type of a query variable by looking at the data source specified in the
from clause. The following example produces the same compiled code as the previous example:
var keyword is useful when the type of the variable is obvious or when it is not that important to explicitly specify nested generic types such as those that are produced by group queries. In general, we recommend that if you use
var, realize that it can make your code more difficult for others to read. For more information, see Implicitly Typed Local Variables.
