在C＃退出foreach循环 [英] Exiting foreach loop in C#

问题描述

foreach (var name in parent.names)
{
    if name.lastname == null)
    {
        Violated = true;
        this.message = "lastname reqd";
    }

    if (!Violated)
    {
        Violated = !(name.firstname == null) ? false : true;
        if (ruleViolated)
            this.message = "firstname reqd";
    }
}

只要违反了是真的，我想离开的在的foreach 立即循环。我该怎么做呢？

Whenever violated is true, I want to get out of the foreach loop immediately. How do I do it?

推荐答案

使用的 破 ;

无关你的问题，我看到你代码行：

Unrelated to your question, I see in your code the line:

Violated = !(name.firstname == null) ? false : true;

在这一行，你拿一个布尔值（name.firstname == NULL）。然后，您应用！运营商给它。然后，如果该值为true，您可以设置侵犯了虚假的;否则为true。所以基本上，触犯被设置为相同的值作为原始表达式（name.firstname == NULL）。为什么不使用，如：

In this line, you take a boolean value (name.firstname == null). Then, you apply the ! operator to it. Then, if the value is true, you set Violated to false; otherwise to true. So basically, Violated is set to the same value as the original expression (name.firstname == null). Why not use that, as in:

Violated = (name.firstname == null);
