Determine If string contains more than 1 value in C#

Let’s say you have a condition like that:

if ((myString.Contains("Value1") && (myString.Contains("Value2")) && (myString.Contains("Value3")))    
{    
...
}

Basically, you want to check if all of your values are contained in the string . Fortunately (with the help of LINQ), this can by translated almost literally into C#:

var values = new String[] {"Value1", "Value2", "Value3"};

if (values.All(v => myString.Contains(v))) 
{
    ...
}

Similarly, if you want to check if any value is contained in the string, you’d substitute All by Any.

if ((myString.Contains("Value1") || (myString.Contains("Value2")) || (myString.Contains("Value3")))    
{
...    
}
//You can translate it to this:
if (values.Any(v => myString.Contains(v))) 
{
    ...
}
