<pre><code>private bool CheckAll()
{
 if ( ....)
 {
 return true;
 }

 return false;
}
</code></pre>

When the if-condition is false the method doesn't know what value should be returned (you probably get an error like "not all paths return a value").

As <a href="https://stackoverflow.com/a/12624764/1376657">CQQL pointed out</a> if you mean to return true when your if-condition is true you could have simply written:

<pre><code>private bool CheckAll()
{
 return (your_condition);
}
</code></pre>

If you have side effects, and you want to handle them before you return, the first (long) version would be required.

++++++++return+false;

}|code-block|syntax|javascript|3065206|但是，由于您使用的是条件的结果作为方法的结果，因此可以将其缩短为|3065207|private+bool+booleanMethod+()+{

Long version:

<pre><code>private bool booleanMethod () {
 if (your_condition) {
 return true;
 } else {
 return false;
 }
}
</code></pre>

But since you are using the outcome of your condition as the result of the method you can shorten it to

<pre><code>private bool booleanMethod () {
 return your_condition;
}
</code></pre>

this how I solved my problem

blocks|key|3065242|text|使用以下代码：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3065243|public+bool+roomSelected()
{
++++foreach+(RadioButton+rb+in+GroupBox1.Controls)
++++{
++++++++if+(rb.Checked+==+true)

Use this code:

<pre><code>public bool roomSelected()
{
 foreach (RadioButton rb in GroupBox1.Controls)
 {
 if (rb.Checked == true)
 {
 return true;
 }
 }
 return false;
}
</code></pre>

blocks|key|4706620|text|一种更简单的方式来解释这个，|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4706621|public+bool+CheckInputs(int+a,+int+b){
public+bool+condition+=+true;

if+(a+>+b+%7C%7C+a+==+b)
{
+++condition+=+false;
}
else
{
+++condition+=+true;
}

return+condition;
}|code-block|syntax|javascript|4706622|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|$]]

A simpler way to explain this,
<pre><code>public bool CheckInputs(int a, int b){
public bool condition = true;

if (a &gt; b || a == b)
{
 condition = false;
}
else
{
 condition = true;
}

return condition;
}
</code></pre>

blocks|key|3065282|text|您缺少else部分。如果所有的条件都是假的，那么else将在你没有从else分支声明和返回任何东西的地方工作。|type|unstyled|depth|inlineStyleRanges|entityRanges|data|3065283|private+bool+CheckALl()
{
++if(condition)
++{
++++return+true
++}
++else
++{
++++return+false
++}
}|code-block|syntax|javascript|3065284|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|$]]

You are missing the else portion. If all the conditions are false then else will work where you haven't declared and returned anything from else branch.

<pre><code>private bool CheckALl()
{
 if(condition)
 {
 return true
 }
 else
 {
 return false
 }
}
</code></pre>

blocks|key|4706653|text|我敢肯定，当你问这个问题时，这两个选项在C#中都不可用，但现在你可以像下面这样做：|type|unstyled|depth|inlineStyleRanges|entityRanges|data|4706654|//+Return+with+ternary+conditional+operator.
private+bool+CheckAll()
{
++++return+(your_condition)+?+true+:+false;
}

//+Alternatively+as+an+expression+bodied+method.
private+bool+CheckAll()+=>+(your_condition)+?+true+:+false;|code-block|syntax|javascript|4706655|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|$]]

I'm sure neither of these options were available in C# when you asked the question but nowadays you can do it like the following:
<pre><code>// Return with ternary conditional operator.
private bool CheckAll()
{
 return (your_condition) ? true : false;
}

// Alternatively as an expression bodied method.
private bool CheckAll() =&gt; (your_condition) ? true : false;
</code></pre>

I was making a method with a <code>bool</code> return value and I had a problem:

This works

<pre><code>private bool CheckAll()
{
 //Do stuff
 return true;
}
</code></pre>

But this dosn't, the method can't detect a return value if it's in a IF-statement.

<pre><code>private bool CheckAll()
{
 if (...)
 {
 return true;
 }
}
</code></pre>

How can I fix this?
