<a href="http://msdn.microsoft.com/en-us/library/7sye83ce.aspx" rel="nofollow">Conditional breakpoints</a> are what you're after, but it appears they are not available in Visual Studio Express.

In Visual Studio (non-Express), the way it works is that you create a conditional breakpoint with an expression equal to your watch value and "Has changed" as your breakpoint condition.

blocks|key|3055220|text|下面是我在中所做的工作。通过按F9或单击最左边的边距来设置断点。然后在出现的红点上右击并选择条件命令。还有其他选择。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3055221|但是，中可能不支持这一点。|3055222|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Here's how I do it in Visual Studio. Set a breakpoint by pressing F9 or clicking in the very left margin. Then right click over the red dot that appears and select the Condition command. There are other options there as well.

However, this may not be supported in Visual Studio Express.

you can use conditional breakpoints

see <a href="http://support.microsoft.com/kb/308469" rel="nofollow">this</a>

blocks|key|3055266|text|您可以编写一个if语句，该语句检查一个更改，并在该if语句中发生一个断点，因此它最初会中断，然后单击“恢复”，它一直持续到到达此断点为止。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3055267|entityMap^0|0^^$0|@$1|2|3|4|5|6|7|D|8|@]|9|@]|A|$]]|$1|B|3|-4|5|6|7|E|8|@]|9|@]|A|$]]]|C|$]]

You could write an if statement that checks for a change and have a break point happen within that if statement, thus it breaks initially, then you click resume, it continues until it hits this break point.

Simple trick for Express edition:

<pre><code>private string myValue;
public string MyValue
{
 set
 {
 if (this.myValue != value) Debugger.Break();
 this.myValue = value;
 }
}
</code></pre>

blocks|key|1500736|text|根据某些运行时条件使用Debugger.Break，或右键单击某个断点，然后选择条件中断->已更改|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1500737|编辑：“快报”中关于这个的不知道|1500738|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|F|8|@]|9|@]|A|$]]|$1|B|3|C|5|6|7|G|8|@]|9|@]|A|$]]|$1|D|3|-4|5|6|7|H|8|@]|9|@]|A|$]]]|E|$]]

Use Debugger.Break based on some runtime condition, or go rightclick on some breakpoint, and choose conditional break -> has changed

Edit: dunno about this in Express

If you want to catch variable change at some breakpoint, as opposed to catching exactly where it was changed, then set the breakpoint, right-click it and choose "Condition". Let's say your variable name is X and it's current value is A. Enter "X != A" in the condition field.

Now the breakpoint will only be hit after X changes to some value other than A.

When debugging my C#, I often want to know when a variable's value changes and then investigate the state of the program.

Currently, I do it like this:

<ol>
<li>Watch-list the offending variable.</li>
<li>Physically spam F10 (shortcut for Step Over) until I see the value change.</li>
</ol>

However, the number of F10s required is annoying.

Surely this has been automated, I thought. But I cannot find this feature in my Microsoft Visual C# Express, which surprises me. After all, the Watch-list does automatically highlight changed values in bright red.

Am I missing something?

How do I "run until this variable changes" when debugging?
