How To: Disable Form Submit on Enter Key Press
http://www.bloggingdeveloper.com/post/Disable-Form-Submit-on-Enter-Key-Press.aspx

The post Enter Key as the Default Button describes how to set the default behaviour for enter key press. However, sometimes, you need to disable form submission on Enter Key press. If you want to prevent it completely, you need to use OnKeyPress handler on <body> tag of your page.

<body OnKeyPress="return disableKeyPress(event)">

<script language="JavaScript">

function disableEnterKey(e)
{
var key;
if(window.event)
key = window.event.keyCode; //IE
else
key = e.which; //firefox

return (key != 13);
}

</script>

If you want to disable form submission when enter key is pressed in an input field, you must use the function above on the OnKeyPress handler of the input field as follows:
<input type=”text” name=”txtInput” onKeyPress=”return disableEnterKey(event)”>

How to disable the Enter key on HTML form

http://webcheatsheet.com/javascript/disable_enter_key.php
Normally when you have a form with several text input fields, it is undesirable that the form gets submitted when the user hits ENTER in a field. Some people are pressing the enter key instead of the tab key to get to the next field. They often do that by accident or because they are accustomed to terminate field input that way. If a browser regards hitting ENTER in a text input field as a request to submit the form immediately, there is no sure way to prevent that.

Add the below script to the <head> section of your page. The following code disables the enter key so that visitors of your web page can only use the tab key to get to the next field.
<script type="text/javascript">

function stopRKey(evt) {
var evt = (evt) ? evt : ((event) ? event : null);
var node = (evt.target) ? evt.target : ((evt.srcElement) ? evt.srcElement : null);
if ((evt.keyCode == 13) && (node.type=="text")) {return false;}
}

document.onkeypress = stopRKey;

</script>

方法一：使用for循环

        int []pins = {9,3,7,2}
        int []copy = new int[pins.length];
        for(int i =0;i!=copy.length;i++)
        {
           copy[i] = pins[i];
         }

方法二：使用数组对象中的CopyTo（）方法

        int []pins = {9,3,7,2}
        int []copy2 = new int[pins.length];
        pins.CopyTo(copy2,0);

方法三：使用Array类的一个静态方法Copy()

        int []pins = {9,3,7,2}
        int []copy3 = new int[pins.length];
        Array.Copy(pins,copy3,copy.Length);

方法四：使用Array类中的一个实例方法Clone（），可以一次调用，最方便，但是Clone（）方法返回的是一个对象，所以要强制转换成恰当的类类型。

int []pins = {9,3,7,2}
int []copy4 = (int [])pins.Clone();
