Definisi

Ruang nama:

System.Linq.Expressions

Rakitan:

UnaryExpression Membuat yang mewakili kenaikan nilai ekspresi sebesar 1.

Overload

Increment(Expression, MethodInfo)	UnaryExpression Membuat yang mewakili kenaikan ekspresi dengan 1.
Increment(Expression)	UnaryExpression Membuat yang mewakili kenaikan nilai ekspresi sebesar 1.

Increment(Expression, MethodInfo)

Sumber:

UnaryExpression.cs

UnaryExpression Membuat yang mewakili kenaikan ekspresi dengan 1.

public:
 static System::Linq::Expressions::UnaryExpression ^ Increment(System::Linq::Expressions::Expression ^ expression, System::Reflection::MethodInfo ^ method);

public static System.Linq.Expressions.UnaryExpression Increment (System.Linq.Expressions.Expression expression, System.Reflection.MethodInfo? method);

static member Increment : System.Linq.Expressions.Expression * System.Reflection.MethodInfo -> System.Linq.Expressions.UnaryExpression

Public Shared Function Increment (expression As Expression, method As MethodInfo) As UnaryExpression

Parameter

expression

Expression

Kenaikan Expression .

method

MethodInfo

MethodInfo yang mewakili metode penerapan.

Mengembalikan

UnaryExpression

UnaryExpression yang mewakili ekspresi yang dinaikkan.

Keterangan

Ekspresi ini berfungsi dan tidak mengubah nilai objek yang diteruskan ke dalamnya.

Increment(Expression)

Sumber:

UnaryExpression.cs

public:
 static System::Linq::Expressions::UnaryExpression ^ Increment(System::Linq::Expressions::Expression ^ expression);

public static System.Linq.Expressions.UnaryExpression Increment (System.Linq.Expressions.Expression expression);

static member Increment : System.Linq.Expressions.Expression -> System.Linq.Expressions.UnaryExpression

Public Shared Function Increment (expression As Expression) As UnaryExpression

Parameter

expression

Expression

Kenaikan Expression .

Mengembalikan

UnaryExpression

UnaryExpression yang mewakili ekspresi yang dinaikkan.

Contoh

Contoh kode berikut menunjukkan cara membuat ekspresi yang mewakili operasi kenaikan.

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

// This expression represents an increment operation.
double num = 5.5;
Expression incrementExpr = Expression.Increment(
                            Expression.Constant(num)
                        );

// Print out the expression.
Console.WriteLine(incrementExpr.ToString());

// The following statement first creates an expression tree,
// then compiles it, and then executes it.
Console.WriteLine(Expression.Lambda<Func<double>>(incrementExpr).Compile()());

// The value of the variable did not change,
// because the expression is functional.
Console.WriteLine("object: " + num);

// This code example produces the following output:
//
// Increment(5.5)
// 6.5
// object: 5.5

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

Dim num As Double = 5.5
' This expression represents an increment operation. 
Dim incrementExpr As Expression = Expression.Increment(
                            Expression.Constant(num)
                        )

' Print the expression.
Console.WriteLine(incrementExpr.ToString())

' The following statement first creates an expression tree,
' then compiles it, and then executes it.
Console.WriteLine(Expression.Lambda(Of Func(Of Double))(incrementExpr).Compile()())

' The value of the variable did not change,
' because the expression is functional.
Console.WriteLine("object: " & num)

' This code example produces the following output:
'
' Increment(5.5)
' 6.5
' object: 5.5

Keterangan

Ekspresi ini berfungsi dan tidak mengubah nilai objek yang diteruskan ke dalamnya.
