How to read and write files on uwp platform

I mount the script in unity, read out the location of the GameObject and write it to a TXT file. It works well in editing state. However, an error is reported or does not run after it is released to uwp. Is there a good solution?

 

My main problem now is that t

he code​

which write in #if NETFX_CORE does not run. Even if I only write a simple output statement, the console will not output anything in debug mode. An error is also reported for asynchronism under uwp~

 

My version is 2019.3.6f. As shown in the picture, this is what I wrote. But there was no reaction. After being released to the uwp platform, the console still has no output. Is there something wrong with my settings?

 

I tried. No response.

Code (CSharp):

1.     void Update()
2.     {
3. #if ENABLE_WINMD_SUPPORT
4.    Debug.Log("print");
5. #endif
6.  
7.     }

 

Its output appears in the UnityPlayer.log . But my question is why it doesn't appear in the development console of uwp? There is also a problem. The C # version of unity does not support async / await asynchronous mechanism (which must be used by storagefile) which was born in 4.5. How to solve the problem of reading and writing?

 

development console :
I write this with system io. In UnityPlayer.log There is no debug information output in, and the file is not created successfully.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using UnityEngine;
4. using System.IO;
5.  
6. public class writefile : MonoBehaviour
7. {
8.  
9.     string gameobjectStr = string.Empty;
10.     int i = 0;
11.     public GameObject GameObject1;
12.     float timer = 0;
13.  
14.     public void WriteFileByLine(string file_path, string file_name, string str_info)
15.  
16.     {
17.  
18.         StreamWriter sw;
19.  
20.         if (!File.Exists(file_path + "//" + file_name))
21.  
22.         {
23.  
24.             sw = File.CreateText(file_path + "//" + file_name);
25.  
26.             Debug.Log("Success！" + file_path);
27.  
28.         }
29.  
30.         else
31.  
32.         {
33.  
34.             sw = File.AppendText(file_path + "//" + file_name);
35.  
36.         }
37.  
38.         sw.WriteLine(str_info);
39.  
40.         sw.Close();
41.  
42.         sw.Dispose();
43.  
44.     }
45.  
46.  
47.  
48.     public void WriteFileByLine1(string file_path, string file_name, string str_info)
49.  
50.     {
51.  
52.         StreamWriter sw;
53.  
54.         FileInfo file_info = new FileInfo(file_path + "//" + file_name);
55.  
56.         if (!file_info.Exists)
57.  
58.         {
59.  
60.             sw = file_info.CreateText();
61.  
62.             Debug.Log("Success1！" + file_path);
63.  
64.         }
65.  
66.         else
67.  
68.         {
69.  
70.             sw = file_info.AppendText();
71.  
72.         }
73.  
74.         sw.WriteLine(str_info);
75.  
76.         sw.Close();
77.  
78.         sw.Dispose();
79.  
80.     }
81.     // Start is called before the first frame update
82.     void Start()
83.     {
84.        
85.     }
86.  
87.     // Update is called once per frame
88.     void Update()
89.     {
90.         if (timer >= 1f)
91.         {
92.             timer = 0;
93.         }
94.         timer += Time.fixedDeltaTime;
95.  
96.         //cameraStr = i + "\t" + camera.transform.position.x.ToString("#0.0000") + "\t" + camera.transform.position.y.ToString("#0.0000") + "\t" + camera.transform.position.z.ToString("#0.0000") + "\t" + timer;
97.         gameobjectStr = i + "\t" + GameObject1.transform.position.x.ToString("#0.0000") + "\t" + GameObject1.transform.position.y.ToString("#0.0000") + "\t" + GameObject1.transform.position.z.ToString("#0.0000") + "\t" + timer;
98.         WriteFileByLine(Application.persistentDataPath, "gamebject.txt", gameobjectStr);
99.         WriteFileByLine1(Application.persistentDataPath, "gamebject1.txt", gameobjectStr);
100.     }
101. }
102.  

 

I use Windows.Storage API to write, the result reports the following error.

Code (CSharp):

1. using System.Collections;
2. using System.Collections.Generic;
3. using System.Diagnostics;
4. using System.IO;
5. using System.Text;
6. using System.Threading;
7. using System.Threading.Tasks;
8. using UnityEngine;
9. #if ENABLE_WINMD_SUPPORT
10. using Windows.Storage;
11. using Windows.Storage.Streams;
12. using System.Linq;
13. #endif

Error statement:

Code (CSharp):

1.     public async Task create_ApplicationData(string fileName)
2.     {
3. #if ENABLE_WINMD_SUPPORT
4.         StorageFolder folder = ApplicationData.Current.LocalFolder;
5.  
6.         file_demonstration = await folder.CreateFileAsync(fileName);
7. #endif
8.     }

 

Thank you very much. I succeeded

 

Excuse me, how to write code in unity and make it become the uwp platform, and then open and run other. Exe programs in uwp?
