什么是VB.net相当于这个C＃命令

Question

var safeMode = new SafeMode(other) { WMode = "majority" };

我在http://www.mongodb.org/display/DOCS/CSharp+Driver+Tutorial#CSharpDriverTutorial-C%23Driverversionv1.4.x

中多次看到此表单

{ WMode = "majority" }是我不熟悉的。它是代码，集合初始化器还是什么？

它的作用是调用SafeMode的构造函数。我不知道你可以在那之后添加括号。那是“代码”还是什么？

Answer 1

它被称为object初始化（MSDN - Overview of Visual Basic 9.0 - object-initializer）。

Dim objSafeMode = New SafeMode(other) With { .WMode = "majority" }

Answer 2

这是C＃语法的一部分。以下是编程指南的链接：

示例：

Cat cat = new Cat { Age = 10, Name = "Fluffy" };

Answer 3

语法称为Object Initializers。

等效的vb.net代码可以是这个完整的代码

Dim safeMode as New SafeMode(other)
With safeMode
 .WMode = "Majority"
End With

或使用对象初始化程序语法。

Dim safeMode as New SafeMode(other) With { .WMode = "Majority" }
