Of course the line in question must have some other typos in it, because it won\u2019t compile at all.<\/p>\n<p>Regardless, you don\u2019t really need that line anyway (the variable isn\u2019t used anywhere else). If you remove it, your code should work as expected.<\/p>\n<p>The one change I would make is to not hard-code the year portion but instead use the year specified in the <code>date<\/code> parameter. This way the method will work in future years. Even better would be to read the peak date ranges from some other data source, so they can be modified without having to recompile the code. But the basic idea I\u2019m suggesting would look like this:<\/p>\n<pre><code>public bool IsInPeakSeason(DateTime date)\n{\n    var startPeak = new DateTime(date.Year, 06, 15);\n    var endPeak = new DateTime(date.Year, 08, 15);\n    return date &gt;= startPeak &amp;&amp; date &lt; endPeak;\n}\n<\/code><\/pre>\n<\/div>\n<div class=\"mt24\"><\/div>\n<\/div>\n<p> <span class=\"d-none\" itemprop=\"commentCount\">0<\/span> <\/p>\n<\/div>\n<\/div>\n<p>solved Use of unassigned local variable when trying to return bool <\/p>\n<p><script async src=\"https:\/\/pagead2.googlesyndication.com\/pagead\/js\/adsbygoogle.js?client=ca-pub-1088640234840270\" crossorigin=\"anonymous\"><\/script><br \/>\n<script><\/p>\n<p><\/script><\/div>\n<p>[ad_2]<\/p>\n<p>When trying to return a boolean value from a method, you may encounter an error stating that an unassigned local variable is being used. This is because the compiler does not recognize the boolean value as a valid return type. To fix this issue, you must assign a value to the boolean variable before returning it.<\/p>\n<p>For example, if you have a method that returns a boolean value, you must assign a value to the boolean variable before returning it. The following code shows how to do this:<\/p>\n<pre>\npublic bool MyMethod()\n{\n    bool result;\n    \/\/ Do something here\n    result = true; \/\/ Assign a value to the boolean variable\n    return result; \/\/ Return the boolean variable\n}\n<\/pre>\n<p>By assigning a value to the boolean variable before returning it, the compiler will recognize the boolean value as a valid return type.
