ArrayIndex(System.Linq.Expressions.Expression,System.Linq.Expressions.Expression[])

Creates a System.Linq.Expressions.MethodCallExpression that represents applying an array index operator to a multidimensional array.

Syntax

public static MethodCallExpression ArrayIndex (Expression array, params Expression[] indexes)

Parameters

array
An array of System.Linq.Expressions.Expression instances - indexes for the array index operation.
indexes
An array of System.Linq.Expressions.Expression objects to use to populate the MethodCallExpression.Arguments collection.

Returns

A System.Linq.Expressions.MethodCallExpression that has the Expression.NodeType property equal to ExpressionType.Call and the MethodCallExpression.Object and MethodCallExpression.Arguments properties set to the specified values.

Remarks

Each element of indexes must have Expression.Type equal to int. The Expression.Type property of array must represent an array type whose rank matches the number of elements in indexes.

If the rank of array.Type is 1, this method returns a System.Linq.Expressions.BinaryExpression. The BinaryExpression.Left property is set to array and the BinaryExpression.Right property is set to the single element of indexes. The Expression.Type property of the System.Linq.Expressions.BinaryExpression represents the element type of array.Type.

If the rank of array.Type is more than one, this method returns a System.Linq.Expressions.MethodCallExpression. The MethodCallExpression.Method property is set to the System.Reflection.MethodInfo that describes the public instance method Get on the type represented by the Expression.Type property of array.
