Add a keypress event and trap the enter key

Programmatically it looks kinda like this:

<pre><code>//add the handler to the textbox
this.textBox1.KeyPress += new System.Windows.Forms.KeyPressEventHandler(CheckEnterKeyPress);
</code></pre>

Then Add a handler in code...

<pre><code>private void CheckEnterKeyPress(object sender, System.Windows.Forms.KeyPressEventArgs e)
{
 if (e.KeyChar == (char)Keys.Return)

 {
 // Then Do your Thang
 }
}
</code></pre>

blocks|key|1672727|text|您可以将此代码放入FormLoad事件中：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1672728|textBox1.KeyPress+%2B=+(sndr,+ev)+=>+

You can drop this into the FormLoad event:

<pre><code>textBox1.KeyPress += (sndr, ev) =&gt; 
{
 if (ev.KeyChar.Equals((char)13))
 {
 // call your method for action on enter
 ev.Handled = true; // suppress default handling
 }
};
</code></pre>

blocks|key|1669713|text|为了将该函数与textbox的按键事件链接起来，在表单的designer.cs中添加以下代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1669714|+this.textbox1.KeyDown+%2B=+new+System.Windows.Forms.KeyEventHandler(this.OnKeyDownHandler);|code-block|syntax|javascript|1669715|现在在相同格式的cs文件中定义函数'OnKeyDownHandler‘：|1669716|private+void+OnKeyDownHandler(object+sender,+KeyEventArgs+e)
{

++++if+(e.KeyCode+==+Keys.Enter)
++++{
+++++++//enter+key+has+been+pressed

Inorder to link the function with the key press event of the textbox add the following code in the designer.cs of the form:

<pre><code> this.textbox1.KeyDown += new System.Windows.Forms.KeyEventHandler(this.OnKeyDownHandler);
</code></pre>

Now define the function 'OnKeyDownHandler' in the cs file of the same form:

<pre><code>private void OnKeyDownHandler(object sender, KeyEventArgs e)
{

 if (e.KeyCode == Keys.Enter)
 {
 //enter key has been pressed
 // add your code
 }

}
</code></pre>

blocks|key|1672778|text|如果你想让某个按钮在程序执行时处理Enter，只需将窗体的AcceptButton属性指向该按钮即可。|type|unstyled|depth|inlineStyleRanges|offset|length|style|BOLD|entityRanges|data|1672779|例如：this.AcceptButton+=+StartBtn;|CODE|1672780|entityMap^0|F|10|0|0|W|3|T|0^^$0|@$1|2|3|4|5|6|7|K|8|@$9|L|A|M|B|C]]|D|@]|E|$]]|$1|F|3|G|5|6|7|N|8|@$9|O|A|P|B|C]|$9|Q|A|R|B|H]]|D|@]|E|$]]|$1|I|3|-4|5|6|7|S|8|@]|D|@]|E|$]]]|J|$]]

In cases you want some button to handle Enter while program is executing, just point the AcceptButton property of the form to the button.
E.g.: <code>this.AcceptButton = StartBtn;</code>

blocks|key|2104306|text|如下所示设置KeyPress事件：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2104307|this.tMRPpart.KeyPress+%2B=+new+System.Windows.Forms.KeyPressEventHandler(this.tMRPpart_KeyPress);|code-block|syntax|javascript|2104308|然后，您可以执行操作，包括检测事件中的“enter”键-|2104309|private+void+tMRPpart_KeyPress(object+sender,+KeyPressEventArgs+e)

++++++++{
++++++++++++//+Move+to+next+control

}|2104310|在我的例子中，如果用户按下enter，我希望应用程序跳转到下一个字段。|2104311|entityMap^0|0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|O|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|Q|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|R|8|@]|9|@]|A|$E|F]]|$1|K|3|L|5|6|7|S|8|@]|9|@]|A|$]]|$1|M|3|-4|5|6|7|T|8|@]|9|@]|A|$]]]|N|$]]

Set the KeyPress event like this:
<pre><code>this.tMRPpart.KeyPress += new System.Windows.Forms.KeyPressEventHandler(this.tMRPpart_KeyPress);
</code></pre>
Then you can perform actions including detecting the 'enter' key in the event -
<pre><code>private void tMRPpart_KeyPress(object sender, KeyPressEventArgs e)
{
 // force any lower case characters into capitals
 if (e.KeyChar &gt;= 'a' &amp;&amp; e.KeyChar &lt;= 'z')
 e.KeyChar -= (char)32;

 // If user presses return, tab to next tab stop
 if (e.KeyChar == (char)Keys.Return)
 {
 if (sender is Control)
 {
 // Move to next control
 SelectNextControl((Control)sender, true, true, true, true);
 }
 }
}
</code></pre>
In my case I wanted the application to tab to the next field if the user pressed enter.

What is definitively the best way of performing an action based on the user's input of the Enter key (<code>Keys.Enter</code>) in a .NET <code>TextBox</code>, assuming ownership of the key input that leads to suppression of the Enter key to the TextBox itself (e.Handled = true)?

Assume for the purposes of this question that the desired behavior is not to depress the default button of the form, but rather some other custom processing that should occur.

根据用户在.NET TextBox中输入的Enter键(Keys.Enter)执行操作的最佳方式是什么(假设拥有导致取消TextBox本身Enter键的键输入的所有权) (e.Handled = true)？出于这个问题的目的，假设所需的行为不是按下窗体的默认按钮，而是应该发生的一些其他自定义处理。
