Exemplos

O exemplo seguinte demonstra o uso de CodePrimitiveExpression para representar valores de vários tipos primitivos.

// Represents a string.
CodePrimitiveExpression stringPrimitive = new CodePrimitiveExpression("Test String");
// Represents an integer.
CodePrimitiveExpression intPrimitive = new CodePrimitiveExpression(10);
// Represents a floating point number.
CodePrimitiveExpression floatPrimitive = new CodePrimitiveExpression(1.03189);
// Represents a null value expression.
CodePrimitiveExpression nullPrimitive = new CodePrimitiveExpression(null);

' Represents a string.
Dim stringPrimitive As New CodePrimitiveExpression("Test String")
' Represents an integer.
Dim intPrimitive As New CodePrimitiveExpression(10)
' Represents a floating point number.
Dim floatPrimitive As New CodePrimitiveExpression(1.03189)
' Represents a null value expression.
Dim nullPrimitive As New CodePrimitiveExpression(Nothing)

Observações

CodePrimitiveExpression pode ser usado para representar uma expressão que indica um valor de tipo de dado primitivo.

A Value propriedade especifica o valor do tipo de dado primitivo a representar.

Tipos de dados primitivos que podem ser representados usando CodePrimitiveExpression ; nullstring; inteiros assinados de 16, 32 e 64 bits; e números de ponto flutuante de precisão simples e dupla.
