Find an array in a string

I am working with the Selenium API in C#. I try to read a script and get the needed values from that.

string attackable_villages = web.FindElement(By.XPath("//*[@id='content_value']/script[1]")).GetAttribute("innerHTML");
richTextBox1.Text = attackable_villages;

The result I get:

result.scrollBound = {
    x_min: 0,
    x_max: 999,
    y_min: 0,
    y_max: 999
};

result.tileSize = [53, 38];

result.screenKey = 'bf14559d';
result.topoKey = 4133874391;

and many more..

But there is this:

result.thisiswhatiwant= [1value1, 1value2, 1value3, 1value4..], [2value1, 2value2, 2value3, ...], [...]

How can I just get that array without the rest and split all elements after "],"

I hope you can help me!
