unity工具开发

1.EditorWindow通过拖拽获取文件夹或者文件路径

#region 拖拽相关

Rect rect4 = EditorGUILayout.GetControlRect();

//将上面的框作为文本输入框

selectPath = EditorGUI.TextField(rect4, selectPath);

//subPath = EditorGUILayout.TextField(subPath);

//如果鼠标正在拖拽中或拖拽结束时，并且鼠标所在的位置在文本输入框内

if ((Event.current.type == EventType.DragUpdated || Event.current.type == EventType.DragExited) && rect4.Contains(Event.current.mousePosition))

{

DragAndDrop.visualMode = DragAndDropVisualMode.Generic;

if (DragAndDrop.paths != null && DragAndDrop.paths.Length > 0)

{

selectPath = DragAndDrop.paths[0];

}

}

#endregion

2.反序列化

public static Object GetObjectFromBytes(byte[] datas)

{

if (datas == null || datas.Length == 0)

return null;

BinaryFormatter bf = new BinaryFormatter();

using (MemoryStream stream = new MemoryStream(datas, 0, datas.Length))

{

Object obj = bf.Deserialize(stream) as Object;

stream.Dispose();

return obj;

}

}

3.保存到文件

bool SaveLocalFile(string path, byte[] data)

{

if (File.Exists(path))

File.Delete(path);

using (FileStream fs = new FileStream(path, FileMode.CreateNew))

{

if (fs == null)

return false;

fs.Write(data, 0, data.Length);

AssetDatabase.Refresh();

AssetDatabase.ImportAsset(path, ImportAssetOptions.ForceUpdate);

return true;

}

}

4.取文件

public byte[] GetLocalFile(string path)

{

if (File.Exists(path) == false)

return null;

using (FileStream fs = new FileStream(path, FileMode.Open))

{

if (fs == null || fs.Length == 0)

return null;

byte[] data = new byte[fs.Length];

fs.Read(data, 0, data.Length);

return data;

}

}

5.调用windows系统dialog 选择文件夹

string fullDirPath = new String(charArray);

return fullDirPath;//这个就是选择的目录路径。
