实现功能：

• 自动创建继承ScriptableObject的C#数据类，每条Excel的数据，都有对应的字段的Get函数； 

• 自动创建每个Excel的Asset生成类和生成函数，用于自动生成Asset文件

• 使用Asset生成类自动序列化Excel数据到Asset文件，可直接在项目运行时加载使用

实现原理：

Excel配置格式：

• 第1行对应特殊标记（可以设置有效性，指定要创建的文件）
• 第2行对应中文说明（作为第3行字段的注释）
• 第3行对应字段名称（自动创建的字段名称）
• 第4行对应字段类型（自动创建的字段类型，与字段名称一一对应）
• 第5行及以后对应字段值（所有数据，以行为单位解析、保存数据）
• 第一列固定字段为"id"，是代码中索引每行数据的Key

Excel注释操作：

• 字段名称行，每个字段单元格内容前加"//"，可以注释该字段，不会解析生成到C#类；
• 第一列的单元格内容前加"//"，可以注释一行数据，不会保存到Asset文件中；
• 注释可以用于添加说明行，或剔除指定无用数据。

生成的C#类格式：

行数据类，对应每一行数据：

[Serializable]
public class TestConfigExcelItem : ExcelItemBase
{
	/// <summary>
	/// 数据id
	/// </summary>>
	public int id;
	/// <summary>
	/// 字符串
	/// </summary>>
	public string testString;
	/// <summary>
	/// Int
	/// </summary>>
	public int testInt;
	/// <summary>
	/// Float
	/// </summary>>
	public float testFloat;
}

完整数据类，包含所有行的数据、初始化函数、Get函数：

public class TestConfigExcelData : ExcelDataBase<TestConfigExcelItem>
{
	public TestConfigExcelItem[] items;

	public Dictionary<int,TestConfigExcelItem> itemDic = new Dictionary<int,TestConfigExcelItem>();

	public void Init()
	{
		itemDic.Clear();
		if(items != null && items.Length > 0)
		{
			for(int i = 0; i < items.Length; i++)
			{
				itemDic.Add(items[i].id, items[i]);
			}
		}
	}

	public TestConfigExcelItem GetTestConfigExcelItem(int id)
	{
		if(itemDic.ContainsKey(id))
			return itemDic[id];
		else
			return null;
	}
	#region --- Get Method ---

	public string GetTestString(int id)
	{
		var item = GetTestConfigExcelItem(id);
		if(item == null)
			return default;
		return item.testString;
	}

	// ··· ···

	#endregion
}

目前支持的数据结构：

字符串	testString	字符串数组	testStringArray	字符串二维数组	testStringArray2
Int	testInt	Int数组	testIntArray	Int二维数组	testIntArray2
Float	testFloat	Float数组	testFloatArray	Float二维数组	testFloatArray2
Bool	testBool	Bool数组	testBoolArray	Bool二维数组	testBoolArray2
Enum	枚举名(或枚举值)	testEnum	Enum数组	testEnumArray	Enum二维数组	不支持
Vector2	testVector2	Vector2数组	testVector2Array	Vector2二维数组	testVector2Array2
Vector3	testVector3	Vector3数组	testVector3Array	Vector3二维数组	testVector3Array2
Vector2Int	testVector2Int	Vector2Int数组	testVector2IntArray	Vector2Int二维数组	testVector2IntArray2
Vector3Int	testVector3Int	Vector3Int数组	testVector3IntArray	Vector3Int二维数组	testVector3IntArray2
Color	testColor	Color数组	testColorArray	Color二维数组	testColorArray2
Color32	testColor32	Color32数组	testColor32Array	Color32二维数组	testColor32Array2

因为Unity不能序列化二维数组，这里改成一维数组+结构体的方式实现：

[Serializable]
public struct StringArr
{
    public string[] array;
}

//二维数组表示方式： StringArr[]

Asset数据文件：

在自动生成数据的C#类时，会同步生成Asset文件的创建类，用于自动创建Asset文件并序列化数据。

优点：

• 数据修改后只需要重新一键生成即可
• 每个Excel对应一个类，使用灵活，对Excel限制少
• 自动创建C#类，不需要对每个Excel手动写代码，每条数据对应字段，不需要拆箱装修
• 自动创建ScriptableObject的Asset文件，自动序列化数据，方便查看，可以手动修改调整，不需要每次改动都在Excel里操作
• 在游戏内直接读取Asset的ScriptableObject子类，不需要额外操作，业务层直接调取数据字段

使用方法：

• 按照标准格式配置Excel
• 一键生成C#类、Asset文件
• 项目运行时加载Asset资源，调用Init初始化，Get函数获取对应字段值即可
