Expression.Type Expression.Type Expression.Type Expression.Type Property

Definition

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

public:
 property Type ^ Type { Type ^ get(); };
public Type Type { get; }
member this.Type : Type
Public ReadOnly Property Type As Type

Property Value

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.

// 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
' 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
