字符串未传递给 c# wpf 中的另一个类

Question

编辑：我通过将字符串传递给公共静态字符串解决了这个问题：我将公共字符串自动保存路径更改为公共静态字符串自动保存路径。在第二节课中，我替换了公共字符串attributesFilePath =“nothing”;公共静态字符串 autosavePath = $"{careerProfile.autosavePath}";

我正在创建一个软件，它基本上根据用户输入的配置文件用户名修改 .json 文件。所有代码都根据输入的用户名成功检索 .json 文件的文件位置。但是，无论我做什么，我都无法将“autosavePath”字符串从第一个类（保存路径）传递到第二个类。此外，我还设置了一个日志系统来尝试跟踪发生的情况，一旦第二类中的代码开始，字符串就保持为空，而字符串保存第一类中的正确路径。

第一堂课：

public class firstClass
{
    public bool isValidProfile = false;
    public bool dirsExist = false;
    public string autosavePath = "";

    public async Task checkProfileAsync(MainWindow mw)
    {
        rearrangeSaveDirs rearrangeDirs = new rearrangeSaveDirs();
        playerAttributes playerAttributes = new playerAttributes();

        await Task.Run(() => 
        {
                    if (Directory.Exists(profilePath))
                    {
                        Debug.WriteLine($"profile {profileName} exists at {profilePath}");
                        logger.log($"profile {profileName} exists at {profilePath}");

                        isValidProfile = true;
                        logger.log("isValidProfile = true");

                        //make sure that the autosave files were successfully rearranged
                        
                        
                        bool success = rearrangeDirs.rearrangeAutosaves(this);
                        
                        if (success)
                        {
                            logger.log("rearrangeAutosaves function returned 'success'; setting dirsExist = true");

                            dirsExist = true;

                            

                        }
                        

                        Task.Delay(1500).Wait();
                    }
                    else
                    {
                        Debug.WriteLine($"profile {profileName} was not found at {profilePath}");
                        logger.log($"profile {profileName} was not found at {profilePath}");
                        isValidProfile = false;
                        logger.log("isValidProfile = false");
                    }
                }
            }
        });


        
        if (isValidProfile == true && dirsExist == true)
        {
            autosavePath = rearrangeDirs.keptAutosaveDir;
            logger.log($"autosavePath = {autosavePath}");

            logger.log("isValidProfile returned true and dirsExist returned true");
            await Task.Run(() =>
            {
                Thread.Sleep(5500);
            });
            playerAttributes.attributesFilePath = autosavePath;
            MessageBox.Show($"{autosavePath}");
        }

    }
}

这是第二堂课：

public class playerAttributes
{
    //file path to the attributes file
    public string attributesFilePath = "nothing";


    public void modifyAttributes(string option, double value)
    {
        //modify the playerAttributes.json file correspondingly to what the user selected
        logger.log($"attributesFilePath was set to {attributesFilePath}"); 
        if (Directory.Exists(attributesFilePath))
        {
          //continue function
        }
        else
        {
          logger.log($"Directory attributesFilePath does not exist: {attributesFilePath}");
    errorBox.sendMSB();
        }

    }
}

这是日志显示的内容： 6/07/2024 3:24:48 PM：rearrangeAutosaves 函数返回“成功”；设置 dirsExist = true

6/07/2024 3:06:48 PM: autosavePath = C:\Users\zrylx\AppData\Local\software\setting
