我有一个由以下元素组成的数组：

var schools = new [] {
    new object[]{ new[]{ "1","2" }, "3","4" },
    new object[]{ new[]{ "5","6" }, "7","8" },
    new object[]{ new[]{ "9","10","11" }, "12","13" }
};

我尝试扁平化的真正对象是将数据从 CSV 导入数组数组，然后将其加入字段值：

    var q =
        from c in list
        join p in vocatives on c.Line[name1].ToUpper() equals p.first_name.ToUpper() into ps
        from p in ps.DefaultIfEmpty()
        select new object[] { c.Line,  p == null ? "(No vocative)" : p.vocative, p == null ? "(No sex)" : p.sex }; 

我想展平该字符串数组以获得：

string[] {
    new string[]{ …
