推荐答案

It很难弄清楚你在这里想做什么 - 你的问题不是很清楚。

所以我真的不能给你代码！



假设您有两种形式：Form1和Form2。 Form1有一个文本框。



如果Form1上的按钮打开Form2，你想在From2上设置一个值到文本框的内容：

1）创建一个带有字符串参数的Form2构造函数，并直接用字符串构造它，

或

2）在Form2中创建一个字符串属性，它可以接受该值，

2.1）在创建它之后和调用ShowDialog之前设置Form2实例属性。



如果你想要一个按钮在Form2上从Form1获取一个值然后这有点复杂 - 问我会告诉你。

It''s difficult to work out exactly what you are trying to do here - your question is not very clear.
So I can''t really give you code!

Let''s say you have two forms: Form1 and Form2. Form1 has a textbox.

If a button on Form1 opens Form2 and you want to set a value on From2 to the content of the textbox:
1) Either create a Form2 constructor that take a string parameter, and construct it with the string directly,
or
2) Create a string property in Form2 which can accept the value,
2.1) Set the Form2 instance property after your create it and before you call ShowDialog.

If you want a button on Form2 to fetch a value from Form1 then that is a little more complex - ask and I''ll tell you.
