Expression.NewArrayBounds Method

Definition

Creates a NewArrayExpression that represents creating an array that has a specified rank.

Overloads

NewArrayBounds(Type, Expression[])

Creates a NewArrayExpression that represents creating an array that has a specified rank.

NewArrayBounds(Type, IEnumerable<Expression>)

Creates a NewArrayExpression that represents creating an array that has a specified rank.

NewArrayBounds(Type, Expression[])

Source:
NewArrayExpression.cs
Source:
NewArrayExpression.cs
Source:
NewArrayExpression.cs

Creates a NewArrayExpression that represents creating an array that has a specified rank.

C#
public static System.Linq.Expressions.NewArrayExpression NewArrayBounds(Type type, params System.Linq.Expressions.Expression[] bounds);

Parameters

type
Type

A Type that represents the element type of the array.

bounds
Expression[]

An array of Expression objects to use to populate the Expressions collection.

Returns

A NewArrayExpression that has the NodeType property equal to NewArrayBounds and the Expressions property set to the specified value.

Exceptions

type or bounds is null.

-or-

An element of bounds is null.

The Type property of an element of bounds does not represent an integral type.

Examples

The following example demonstrates how to use the NewArrayBounds method to create an expression tree that represents creating a string array that has a rank of 2.

C#
// Create an expression tree that represents creating a
// two-dimensional array of type string with bounds [3,2].
System.Linq.Expressions.NewArrayExpression newArrayExpression =
    System.Linq.Expressions.Expression.NewArrayBounds(
            typeof(string),
            System.Linq.Expressions.Expression.Constant(3),
            System.Linq.Expressions.Expression.Constant(2));

// Output the string representation of the Expression.
Console.WriteLine(newArrayExpression.ToString());

// This code produces the following output:
//
// new System.String[,](3, 2)

Remarks

The Type property of the resulting NewArrayExpression represents an array type whose rank is equal to the length of bounds and whose element type is type.

The Type property of each element of bounds must represent an integral type.

Creates a NewArrayExpression that represents creating an array that has a specified rank.

C#
public static System.Linq.Expressions.NewArrayExpression NewArrayBounds(Type type, System.Collections.Generic.IEnumerable<System.Linq.Expressions.Expression> bounds);

Parameters

type
Type

A Type that represents the element type of the array.

bounds
IEnumerable<Expression>

An IEnumerable<T> that contains Expression objects to use to populate the Expressions collection.

Returns

A NewArrayExpression that has the NodeType property equal to NewArrayBounds and the Expressions property set to the specified value.

Exceptions

type or bounds is null.

-or-

An element of bounds is null.

The Type property of an element of bounds does not represent an integral type.

    System.Linq.Expressions.Expression.NewArrayBounds(
            typeof(string),
            System.Linq.Expressions.Expression.Constant(3),
            System.Linq.Expressions.Expression.Constant(2));

// Output the string representation of the Expression.
Console.WriteLine(newArrayExpression.ToString());

// This code produces the following output:
//
// new System.String[,](3, 2)
