What's the expected float value out of it? If you see there can be multiple ways to read and thus there is no standard converter for it. You would need to define one of your own based on some rule and then use it.

string=>"0.0.8"
float=>0.0, 0.8, 8.0 => so shared string is not a value 1-1 float convertible value.

You can't convert "0.0.8" into a double or float because those number types only allow one decimal point. If you want to parse this as an actual version you can use the Version Class (System) | Microsoft Learn[^]

C#

string text = _oTable.Rows[0]["Version"].ToString();

if (Version.TryParse(text, out Version version))
{
  // Do something with the version
}
