Assuming you have an array such as
string[][] myData = new string[][] {new string[] {"78", "50", " 5", "15", "10", " 5", "15"},
new string[] {"88", "35", "34", " 5", "66", " 5", "15"}};
then:
foreach (string[] row in myData)
{
Prozess p = new Prozess();
p.one = row[0];
p.two = row[1];
p.three = row[2];
p.four = row[3];
p.five = row[4];
p.six = row[5];
p.seven = row[6];
Persons.Add(p);
}
