How do I return lengths of string in an array?

I have an array of strings and want to output those that are of a certain length from the array.

string[]myArray = {"stringone", "stringtwo", "stringthree"};

I have tried doing

foreach(thing in myArray){
if(thing.length<10){
do stuff
}

@output

But doesnt work. Where am i going wrong? I'm using C# in asp.net.

Many thanks.

Assuming your problem was length instead of Length, you can filter out only the values you need using a Where clause:

string[] myArray = { "stringone", "stringtwo", "stringthree" };

foreach (string thing in myArray.Where(thing => thing.Length < 10))
{
    // Here you'll only iterate values
    // whos length is less than 10
}

you need to specify that thing is a string or var.

Also, you need to capitalize Length.

    public void McTester()
    {
        string[] myArray = { "stringone", "stringtwo", "stringthree" };
        foreach (string thing in myArray)
        {
            if (thing.Length < 10)
            {
                //do stuff
            }
        }
    }

string[] myArray = { "stringone", "stringtwo", "stringthree" };
var lessThan10Length  = myArray.Where(x=> x.Length < 10).ToList();
