需要初始化对象的新实例

Question

以下代码：

        CodeVariableDeclarationStatement variableDeclaration = new CodeVariableDeclarationStatement(
            // Type of the variable to declare.
            typeof(string),
            // Name of the variable to declare.
            "TestString");

生成以下 VB.Net 语句：

Dim TestString As String

我需要进行哪些更改才能使其看起来像这样：

Dim TestString As New StringBuilder()

我对如何显示 NEW 关键字感兴趣。

Answer 1

在构造函数中添加一个 CodeObjectCreateExpression 作为第三个参数：

CodeVariableDeclarationStatement variableDeclaration = new CodeVariableDeclarationStatement(
    // Type of the variable to declare.
    typeof(System.Text.StringBuilder),
    // Name of the variable to declare.
    "TestString",
    // A CodeExpression that indicates the initialization expression for the variable.
    new CodeObjectCreateExpression( typeof(System.Text.StringBuilder), new CodeExpression[] {} )
);
