Expression.Increment Method

Definition

Namespace:

System.Linq.Expressions

Assemblies:

netstandard.dll, System.Linq.Expressions.dll

Creates a UnaryExpression that represents the incrementing of the expression value by 1.

Overloads

Increment(Expression, MethodInfo)	Creates a UnaryExpression that represents the incrementing of the expression by 1.
Increment(Expression)	Creates a UnaryExpression that represents the incrementing of the expression value by 1.

Increment(Expression, MethodInfo)

Source:

UnaryExpression.cs

Creates a UnaryExpression that represents the incrementing of the expression by 1.

C#

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

Parameters

expression

Expression

An Expression to increment.

method

MethodInfo

A MethodInfo that represents the implementing method.

Returns

UnaryExpression

A UnaryExpression that represents the incremented expression.

Remarks

This expression is functional and does not change the value of the object that is passed to it.

Increment(Expression)

Source:

UnaryExpression.cs

Creates a UnaryExpression that represents the incrementing of the expression value by 1.

C#

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

Parameters

expression

Expression

An Expression to increment.

Returns

UnaryExpression

A UnaryExpression that represents the incremented expression.

Examples

The following code example shows how to create an expression that represents an increment operation.

C#

// 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

Remarks

This expression is functional and does not change the value of the object that is passed to it.
