<div>
Try something like this? I only did this for <b>list1</b>. Just adapt it to include <b>list2</b>.<br />

<pre><code id="code-20-42227090-1">List&lt;string&gt; fromList = new List&lt;string&gt;(new string[] { &quot;Sub A&quot;, &quot;Sub B&quot; });
List&lt;string&gt; list1 = new List&lt;string&gt;(new string[] { &quot;Sub A=80&quot;, &quot;Sub D=70&quot; });
List&lt;string&gt; list = list1.Where(c =&gt; fromList.Any(c.Contains)).ToList();
if (list.Count() &gt; 0)
{
    foreach (string item in list)
    {
     Console.WriteLine(item);   
    }
}
else
{
 Console.WriteLine(&quot;false&quot;);
 return false;   
}</code></pre>

List<string> fromList = new List<string>(new string[] { "Sub A", "Sub B" });
List<string> list1 = new List<string>(new string[] { "Sub A=80", "Sub D=70" });
List<string> list = list1.Where(c => fromList.Any(c.Contains)).ToList();

Hi,<br />
<br />
How to find and search list values which is available or not from multiple another lists.<br />
<br />
For example,<br />
<br />
&nbsp;List&lt;string&gt; FromList = new List&lt;string&gt;() { &quot;Sub A&quot;, &quot;Sub B&quot; };<br />
&nbsp; &nbsp; &nbsp; &nbsp; List&lt;string&gt; List1 = new List&lt;string&gt;() { &quot;Sub A=80&quot;, &quot;Sub D=70&quot; };<br />
&nbsp; &nbsp; &nbsp; &nbsp; List&lt;string&gt; List2 = new List&lt;string&gt;() { &quot;Sub B=100&quot;, &quot;Sub C=90&quot; };<br />
<br />
I want to take Fromlist and check this will be available or not in List1 and List2.<br />
<br />
if it is available then it returns result as Sub A=80 and Sub B=100.<br />
<br />
if it is not available in both list (List1 and List2) then it returns false.<br />
<br />

Hi,

How to find and search list values which is available or not from multiple another lists.

For example,

 List<string> FromList = new List<string>() { "Sub A", "Sub B" };
        List<string> List1 = new List<string>() { "Sub A=80", "Sub D=70" };
        List<string> List2 = new List<string>() { "Sub B=100", "Sub C=90" };

I want to take Fromlist and check this will be available or not in List1 and List2.

if it is available then it returns result as Sub A=80 and Sub B=100.

if it is not available in both list (List1 and List2) then it returns false.

LINQ - How to search list values from another multiple list.

Language Integrated Query (LINQ) is a Microsoft .NET Framework component that adds native data querying capabilities to .NET languages, although ports exist for Java, PHP, JavaScript and ActionScript. LINQ extends the language by the addition of query expressions, which are akin to SQL statements, and can be used to conveniently extract and process data from arrays, enumerable classes, XML documents, relational databases, and third-party data sources.
