c# - 如何添加xml架构

Question

我有一个 XML 模式 xsd，我使用 Visual Studio 中的 Xsd2Code 工具将其转换为 cs 文件，

我目前正在做的是， //请按照手写方式忽略语法

Public Method_1()
{
Fruits f = new Fruits();
f.Name = "Mangoes";

Foreach (DataRow row in DataTable)  //assume i am getting rows from database
{
      FruitsCrate fc = new FruitsCrate();
      fc.Id = 2;
      fc..... etc

      f.FruitsCrate.add(fc);  // as fruitCrate is a child node of fruit   
}

Foreach (DataRow row in DataTable)
{
      FruitBasket fb = new FruitBasket();
      fb.id = 2;
      fb....   etc

      f.FruitBaskets.add(fb);  // as fruit basket is child node
}

//a lot of more foreach just like above
}

现在的问题是我想将 foreach 语句放在不同的方法中，所以我不确定如何将不同的 childNodes 添加到父节点，

我想做的是，

Public Method_1()   //hand written code so syntax might not be right
{
   Fruits f = new Fruits();
   f = Method-2();   // ???????????????
   f = Method-3(); 
   f = Method-4(); //...........  won't f value will be reset each time
}

public Fruits Method_2(Fruits f)
{
    foreach(dataRow row in DataTable)
    {
        FruitCrate fc = new FruitCrate();
        fc.propertyA = "aaaa"; etc...

        f.FruitsCrate.add(fc);
    }
   return f;
}

第二种编码方式是手写的，我认为行不通，甚至是不可能的方式
