三：导出数据

此工具支持导出什么语言，区别就在这层，之前的两个步骤，与此步骤都不相关。

简单的说，需要导出的格式就在这里写，lua，java，二进制等等。

目前我将excel数据导出的格式为ScriptableObject，.asset资源文件。

ScriptableObject就是“脚本化对象”，将这类作为存储结构化的数据来使用，并写入Unity的资源.asset文件去存储一组数据，取用的时候直接作为一个数据对象拿来用。

无论我们是创建或读取.asset资源，都需要一个与.asset文件格式对应的scripttableobject类。

所以，我利用步骤二已知数据，导出一个与excel表相对应的ScriptableObject类，然后通过反射，再使用此类导出.asset资源文件。

当然导出的ScriptableObject类，为了与我项目内的数据管理模块相接，所以略微加入了一些方法。

代码写在步骤二中已经提到过的ExportExcelToClient函数中。

[code]            var u8WithoutBom = new System.Text.UTF8Encoding(false);

string csUpName = curFileName.ToUpper().Substring(0, 1) + curFileName.Substring(1);

if (exportType == EXPORT_TYPE_LUA)
{

}
if (exportType == EXPORT_TYPE_JSON)
{

}
if (exportType == EXPORT_TYPE_SCRIPT)
{
////以下为使用excel数据时候使用的C# scriptable脚本
string cPath;
StreamWriter cSw;
cPath = Application.dataPath + _clientEditorPath + "DataTable" + csUpName + ".cs";
if (System.IO.File.Exists(cPath))
{
File.Delete(cPath);
}
cSw = new StreamWriter(cPath, false, u8WithoutBom);
cSw.WriteLine("/*=====================================================");
cSw.WriteLine("* - Editor by tool");
cSw.WriteLine("* - Don't editor by handself");

cSw.Flush();
cSw.Close();
cSw.Dispose();

Debug.Log(curFileName + "  scriptableObject  file  export complete !");
}

导出玩scriptableObject类之后，就是利用反射，创建出.asset资源文件。

[code]            if (exportType == EXPORT_TYPE_ASSET)
{
string className = string.Format("DataTable{0}", csUpName);
Type type = Type.GetType(className);
string eleName = string.Format("{0}Excel", csUpName);
Type eleType = Type.GetType(eleName);

var asset = ScriptableObject.CreateInstance(type);

MethodInfo addMethod = type.GetMethod("AddInfo");

foreach (var pair in dicData)
{
var item = Activator.CreateInstance(eleType);
FieldInfo[] fields = eleType.GetFields();

for (int i = 0; i < index.Count; i++)//循环所有的列数
{
FieldInfo singleField = fields[i];
if (string.IsNullOrEmpty(pair.Value[index[i]]))//某一行的某一列
{
if (dicClientTypes[index[i]] == "string")
{
singleField.SetValue(item, Convert.ChangeType("", typeof(string)));
}
else if (dicClientTypes[index[i]] == "int")
{
singleField.SetValue(item, Convert.ChangeType(0, typeof(int)));
}
else if (dicClientTypes[index[i]] == "array")
{
singleField.SetValue(item, Convert.ChangeType(0, typeof(int[])));
}
}
else
{
if (dicClientTypes[index[i]] == "string")
{
singleField.SetValue(item, Convert.ChangeType(pair.Value[index[i]], typeof(string)));
}
else if (dicClientTypes[index[i]] == "array")
{
int[] test = GetStringToInt(pair.Value[index[i]]);
singleField.SetValue(item, test);
}
else if (dicClientTypes[index[i]] == "int" || dicClientTypes[index[i]] == "uint" || dicClientTypes[index[i]] == "float")
{
singleField.SetValue(item, Convert.ChangeType(pair.Value[index[i]], typeof(int)));
}
else
throw new Exception("配置了客户端不支持的类型");
}
}
addMethod.Invoke(asset, new object[] { item });
}

string assetPath = "Assets" + _clientPath + "DataTable" + csUpName + ".asset";

AssetDatabase.CreateAsset(asset, assetPath);

AssetDatabase.Refresh();

Debug.Log(curFileName + "  assest  file  export complete !");
}

以上就已经讲解完此导表工具的大致思路跟关键代码了。

以下为导出后的scriptableObject脚本：

以下为.asset资源文件：

简单的说，思路都是一样的，之后无论是想要导出lua、java、二进制等等，只要在导出的时候，编写不同的导出模式，以及跟自己项目中的数据管理模块相接就可以了。

目前，我的小项目中数据管理模块，使用数据的方式，我个人感觉不是很好，在做更好的优化处理，所以看了博客的朋友们，再次提醒，文章志在提供思路。大神们有更好的方式，可以给我留个言，我会努力深入探讨研究的。
