title: NUnit Sequential Attribute with arrays in Values
body: <p>How I can pass <code>string[][]</code> arrays to ValuesAttribute?</p>
  
  <p>I have:</p>
  
  <pre><code>public string[][] Array1 = new[] {new[] {"test1", "test2"}};
  //...
  [Test, Sequential]
  public void SomeTest(
      [Values("val1", "val2", "val3")] string param1, 
      [Values(Array1, Array2, Array3)] string[][] param2) { //... }
  </code></pre>
  
  <p>And I've got <code>Cannot access non-static field "Array1" in static context</code>. Than I mark <code>Array1</code> with <code>static</code> keyword and than I've got <code>An attribute argument must be a constant expression...</code> than I mark it with <code>readonly</code> keyword and still I have <code>An attribute argument must be a constant expression...</code></p>
  
  <p>Is here any way to pass multiple arrays? (Except ugly <code>string[][][]</code> and passing <code>param2</code> indexes of relevant <code>array[][]</code> in <code>array[][][]</code>)</p>
