Question

I have a string array, and it may contain an element with the text “mytext” within the string. eg:

mystringarray
{
    [0] => "hello world";
    [1] => "some of mytext";
}

I also have an array that doesn’t have the mytext text in it.

mystringarray
{
    [0] => "hello world";
    [1] => "some of notmy";
}

My problem is when I use:

string mytextdata = mystringarray.Single<string>(t => t.Contains("mytext")).ToString();

I get an exception for the second array as it can’t find an element that matches the expression.

Is there a quick way I can edit this one line to not throw an exception if it finds nothing, and instead just ignore? I have a lot of these lines and I don’t want to have to wrap each in an if statement.

Apologies if question isn’t clear.

Answer 1

string mytextdata = mystringarray.SingleOrDefault<string>(t => t.Contains("mytext"));

This will return null if nothing is found, otherwise it will return a string, so you don’t need the ToString(). http://msdn.microsoft.com/en-us/library/bb342451.aspx
