Expression.Type Property

Gets the static type of the expression that this Expression represents.

Namespace:  System.Linq.Expressions
Assembly:  System.Core (in System.Core.dll)
Syntax
Visual Basic
Public Overridable ReadOnly Property Type As Type
C#
public virtual Type Type { get; }
Visual C++
public:
virtual property Type^ Type {
	Type^ get ();
}
F#
abstract Type : Type
override Type : Type

Property Value

Type: System.Type
The Type that represents the static type of the expression.
Remarks

The NodeType is the type of the expression tree node, whereas the Type represents the static common language runtime (CLR) type of the expression that the node represents. For example, two nodes with different node types can have the same Type, as shown in the following code example.

Visual Basic

' Add the following directive to your file:
' Imports System.Linq.Expressions  

Dim constExpr As ConstantExpression = Expression.Constant(5)
Console.WriteLine("NodeType: " & constExpr.NodeType.ToString())
Console.WriteLine("Type: " & constExpr.Type.ToString())

Dim binExpr As BinaryExpression = Expression.Add(constExpr, constExpr)
Console.WriteLine("NodeType: " & binExpr.NodeType.ToString())
Console.WriteLine("Type: " & binExpr.Type.ToString())

' This code example produces the following output:
'
' NodeType: Constant
' Type: System.Int32
' NodeType: Add
' Type: System.Int32
C#

// Add the following directive to your file:
// using System.Linq.Expressions;  

ConstantExpression constExpr = Expression.Constant(5);
Console.WriteLine("NodeType: " + constExpr.NodeType);
Console.WriteLine("Type: " + constExpr.Type);

BinaryExpression binExpr = Expression.Add(constExpr, constExpr);
Console.WriteLine("NodeType: " + binExpr.NodeType);
Console.WriteLine("Type: " + binExpr.Type);

// This code example produces the following output:
//
// NodeType: Constant
// Type: System.Int32
// NodeType: Add
// Type: System.Int32
