Queryable.Min<'TSource, 'TResult> Method (IQueryable<'TSource>, Expression<Func<'TSource, 'TResult>>)

 

Invokes a projection function on each element of a generic IQueryable<'T> and returns the minimum resulting value.

Namespace:   System.Linq
Assembly:  System.Core (in System.Core.dll)

static member Min<'TSource, 'TResult> : 
        source:IQueryable<'TSource> *
        selector:Expression<Func<'TSource, 'TResult>> -> 'TResult

Parameters

source
Type: System.Linq.IQueryable<'TSource>

A sequence of values to determine the minimum of.

selector
Type: System.Linq.Expressions.Expression<Func<'TSource, 'TResult>>

A projection function to apply to each element.

Return Value

Type: TResult

The minimum value in the sequence.

Type Parameters

TSource

The type of the elements of source.

TResult

The type of the value returned by the function represented by selector.

Exception Condition
ArgumentNullException

source or selector is null.

This method has at least one parameter of type Expression<'TDelegate> whose type argument is one of the Func<'T, 'TResult> types. For these parameters, you can pass in a lambda expression and it will be compiled to an Expression<'TDelegate>.

The Min<'TSource, 'TResult>(IQueryable<'TSource>, Expression<Func<'TSource, 'TResult>>) method generates a MethodCallExpression that represents calling Min<'TSource, 'TResult>(IQueryable<'TSource>, Expression<Func<'TSource, 'TResult>>) itself as a constructed generic method. It then passes the MethodCallExpression to the Execute<'TResult>(Expression) method of the IQueryProvider represented by the Provider property of the source parameter.

The query behavior that occurs as a result of executing an expression tree that represents calling Min<'TSource, 'TResult>(IQueryable<'TSource>, Expression<Func<'TSource, 'TResult>>) depends on the implementation of the type of the source parameter. The expected behavior is that it invokes selector on each element in source and returns the minimum value.

The following code example demonstrates how to use Min<'TSource, 'TResult>(IQueryable<'TSource>, Expression<Func<'TSource, 'TResult>>) to determine the minimum value in a sequence of projected values.
