什么是启动表单构造函数 [英] What is startup form constructor

问题描述

我需要将以下代码放入启动表单的构造函数中.

Hi,
I need to put following code in the Constructor of my startup form.

JohnKenedy.BusinessSQLEXPRInstaller _ins = new JohnKenedy.BusinessSQLEXPRInstaller("<Installation Display Name>", "localhost", "<New database instance name>", "<new database name>", "<database password>", "<database backup filename>");
if (_ins.IsDone == false) _ins.ShowDialog();
if (_ins.IsRestart == true)
{
Application.Exit();
this.Close();
return;
}

但是我真的不知道构造函数是什么以及如何访问它?
有什么帮助吗?谢谢

But I really donot know what the Constructor is and how to access it?
Any help? Thanks

推荐答案

您应该看一下: http://msdn.microsoft.com/zh-cn/library/ms173115.aspx [ ^ ]

创建类或结构时，将调用其构造函数.构造函数与类或结构具有相同的名称，通常会初始化新对象的数据成员."

示例(在这种情况下，构造函数为public Taxi())

Hi,

You should take a look at this: http://msdn.microsoft.com/en-us/library/ms173115.aspx[^]

"When a class or struct is created, its constructor is called. Constructors have the same name as the class or struct, and usually initialize the data members of the new object."

Example (in this case the constructor is public Taxi())

public class Taxi
{
    public bool isInitialized;
    public Taxi()
    {
        isInitialized = true;
    }
}
