在開發過程中，我們往往需要把資源配在excel表裡進行管理，如果我們的邏輯層是使用lua實現的，那我們就需要一個工具來實現把excel直接轉換為lua可以讀取的table結構

程式碼如下

//-----------------------------------excel轉lua-----------------------------------------------
    [MenuItem("Assets/工具/ExcelToLua", false, 10)]
    public static void XlsTolua()
    {
        Object[] selection 
 
= Selection.GetFiltered(typeof(Object), SelectionMode.Unfiltered);
        if (selection != null && selection.Length > 0)
        {
            for (int i = 0; i < selection.Length; i++)
            {
                string path = AssetDatabase.GetAssetPath(selection[i]);
                MyReadTo(path, selection[i].name);
            }
        }
    }

    
 
public static void MyReadTo(string path, string fileName)
    {
        Debug.Log("ReadExcel path ==> " + path);

        FileStream stream = File.Open(path, FileMode.Open, FileAccess.Read, FileShare.Read);
        if (stream == null)
        {
            Debug.Log("stream is null!!");
        }
        IExcelDataReader excelReader 
 
= ExcelReaderFactory.CreateBinaryReader(stream);
        DataSet result = excelReader.AsDataSet();

        if (result == null)
        {
            Debug.Log("讀取失敗!!");
            return;
        }

        int rows = result.Tables[0].Rows.Count;

        }

            {

            }

            }

        }

        DirectoryInfo cc = Directory.GetParent(path);

    }

                    continue;

        File.WriteAllText(path, LuaContent );

在unity中使用excel轉lua功能還需要匯入c#可以使用的讀取excel所需要的庫檔案

這樣就可以使用以上程式碼了
