You need to escape them by doubling them (verbatim string literal):

<pre><code>string str = @"""How to add doublequotes""";
</code></pre>

Or with a normal string literal you escape them with a <code>\</code>:

<pre><code>string str = "\"How to add doublequotes\"";
</code></pre>

blocks|key|1788957|text|因此，您实际上是在问如何在字符串变量中存储双等值？有两种解决方案：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|1788958|var+string1+=+@"""inside+quotes""";
var+string2+=+"\"inside+quotes\"";|code-block|syntax|javascript|1788959|也许为了让事情变得更清楚一些：|1788960|var+string1+=+@"before+""inside""+after";
var+string2+=+"before+\"inside\"+after";|1788961|entityMap^0|0|0|0|0^^$0|@$1|2|3|4|5|6|7|M|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|N|8|@]|9|@]|A|$E|F]]|$1|G|3|H|5|6|7|O|8|@]|9|@]|A|$]]|$1|I|3|J|5|D|7|P|8|@]|9|@]|A|$E|F]]|$1|K|3|-4|5|6|7|Q|8|@]|9|@]|A|$]]]|L|$]]

So you are essentially asking how to store doublequotes within a string variable? Two solutions for that:

<pre><code>var string1 = @"""inside quotes""";
var string2 = "\"inside quotes\"";
</code></pre>

In order to perhaps make it a bit more clear what happens:

<pre><code>var string1 = @"before ""inside"" after";
var string2 = "before \"inside\" after";
</code></pre>

blocks|key|2002707|text|在双引号前加一个反斜杠()。这应该行得通。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2002708|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|$]]

Put a backslash (\) before the double quotes. That should work.

blocks|key|1789289|text|您可以使用&quot;而不是"。它将由浏览器正确显示。|type|unstyled|depth|inlineStyleRanges|offset|length|style|CODE|entityRanges|data|1789290|entityMap^0|5|6|E|1|0^^$0|@$1|2|3|4|5|6|7|H|8|@$9|I|A|J|B|C]|$9|K|A|L|B|C]]|D|@]|E|$]]|$1|F|3|-4|5|6|7|M|8|@]|D|@]|E|$]]]|G|$]]

You could use <code>&amp;quot;</code> instead of <code>"</code>. It will be displayed correctly by the browser.

blocks|key|2002985|text|如果我正确理解了你的问题，也许你可以试试这个：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2002986|string+title+=+string.Format("<div>\"{0}\"</div>",+"some+text");|code-block|syntax|javascript|2002987|entityMap^0|0|0^^$0|@$1|2|3|4|5|6|7|I|8|@]|9|@]|A|$]]|$1|B|3|C|5|D|7|J|8|@]|9|@]|A|$E|F]]|$1|G|3|-4|5|6|7|K|8|@]|9|@]|A|$]]]|H|$]]

If I understand your question properly, maybe you can try this:

<pre><code>string title = string.Format("&lt;div&gt;\"{0}\"&lt;/div&gt;", "some text");
</code></pre>

blocks|key|2003039|text|如果你必须经常这样做，并且你想让代码更简洁，你可能会想要有一个扩展方法。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|2003040|这是非常明显的代码，但我仍然认为它可以很有用的抓住它，让你节省时间。|2003041|++///+<summary>

If you have to do this often and you would like this to be cleaner in code, you might like to have an extension method for this.
This is really obvious code, but still I think it can be useful to grab it and make you save time.
<pre><code> /// &lt;summary&gt;
 /// Put a string between double quotes.
 /// &lt;/summary&gt;
 /// &lt;param name=&quot;value&quot;&gt;Value to be put between double quotes ex: foo&lt;/param&gt;
 /// &lt;returns&gt;double quoted string ex: &quot;foo&quot;&lt;/returns&gt;
 public static string AddDoubleQuotes(this string value)
 {
 return &quot;\&quot;&quot; + value + &quot;\&quot;&quot;;
 }
</code></pre>
Then you may call foo.AddDoubleQuotes() or &quot;foo&quot;.AddDoubleQuotes(), on every string you like.

Another note:
<pre><code> string path = @&quot;H:\\MOVIES\\Battel SHIP\\done-battleship-cd1.avi&quot;;
 string hh = string.Format(&quot;\&quot;{0}\&quot;&quot;, path);
 Process.Start(@&quot;C:\Program Files (x86)\VideoLAN\VLC\vlc.exe &quot;, hh + &quot; ,--play&quot;);
</code></pre>
The real value of <code>hh</code>, as passed, will be &quot;H:\MOVIES\Battel SHIP\done-battleship-cd1.avi&quot;.
When needing double double literals, use: @&quot;H:\MOVIES\Battel SHIP\done-battleship-cd1.avi&quot;;
Instead of: @&quot;H:\MOVIESBattel SHIP\done-battleship-cd1.avi&quot;;
Because the first literals is for the path name and then the second literals are for the double quotation marks.
