消息框中有两个值? [英] Two values in message box?

问题描述

你好，
如果要在一个消息框中显示两个值，该怎么办?
我的意思是:

Hello,
What should I do if I want to show two values in one message box?
I mean something like:

MessageBox.Show("Your name and age will be: " + name +age ,"New guy");

但这只会将两个字符串拆分在一起，因此没有用.

But this will only split two strings together so it''s useless.

推荐答案

连接字符串(使用+)通常被认为是不好的做法.

使用string.Format().这允许您提供任意数量的位"以插入到字符串中，并允许您指定在何处以及使用哪种格式

在上面的示例中，您需要:

concatenating strings (using +) is generally considered bad practice.

use string.Format(). This allows you to provide any number of ''bits'' to insert into a string and allows you to specify where, and what formatting to use

in your above example you would need:

MessageBox.Show(string.Format("Your name and age will be: {0}{1}",name,age) ,"New guy");

使用此...

Use this...

MessageBox.Show("Your name and age will be: " + name +" "+ age ,"New guy");

或
像这样使用String.Formate函数...

OR
Use String.Formate function like this...

MessageBox.Show(string.Format("Your name and age will be: {0}{1}",name,age) ,"New guy");

我不是说英语的人，所以我可能会错过这里的重点，但我只是不要理解将某物分开"的意思.

对于快速消息框，您可以执行以下操作:

I''m not a native English speaker, so I might miss the important point here, but I just don''t get what "splitting something together" could mean.

For a quick message box you can do this:

MessageBox.Show(
    "InitialStringLiteral"
        + integerVarialbe.ToString()
        + "IntermediateStringLiteral"
        + anotherVariable.ToString()
        + "EvenMoreStringLiteralStuff",
    "HeadingAfterTheComma"
);

您甚至可以定义将显示哪些按钮和图标.只需参见 http://msdn.microsoft.com/en-us/library/system.windows.forms.messagebox.show.aspx [ StringBuilder [ ^ ].

You can even define what buttons and icon will be shown. Just see http://msdn.microsoft.com/en-us/library/system.windows.forms.messagebox.show.aspx[^]

Aside from the message box, if you want to concatenate large amounts of strings, consider using a StringBuilder[^].
