背景：我正在为大学构建一个项目，编程并不是我真正的“专业领域”。它是一个基于 C# (Visual Studio) 构建的 GUI。 Porblem：我尝试制作一个数据记录器，它应该注册用户所做的一切（以及时间戳）并将其保存在 .csv 文件中，但我似乎无法让程序来创建它。一旦我关闭应用程序，它应该会显示在我的桌面上，并记录我所做的事情。如果这里的任何人都可以检查并“看看它是否有意义”，也许可以指出哪里是错误的，那就太好了。
PD：英语不是我的母语，抱歉。
这是我认为存在错误的代码：

我可以看到一些问题。首先，从小事做起，而不是试图解决“完整”的问题。如果您想保存 CSV 文件，它只是一个逗号分隔的文件，因此无需创建 Excel 文档。你在那里引入的步骤只会让你迷失方向。例如，您正在创建 Excel 文档并通过以下方式保存：
workbook.SaveAs("RegistroGimb.xlsx")
...但是您想将其转换为您传递的 CSV：
string desktopPath = Environment.GetFolderPath(Environment.SpecialFolder.Desktop);
string filePath = Path.Combine(desktopPath, "RegistroGimb.csv");
string csvFilePath = Path.ChangeExtension(filePath, ".csv");
ConvertXlsxToCsv(filePath, csvFilePath);
请注意，您的“文件路径”不是您保存 XLSX 的文件名，并且可能不在桌面文件夹中。默认情况下，文件将保存在工作文件夹中，该文件夹通常与您的应用程序运行所在的文件夹相同。
以最简单的方式保存 CSV 就像打开文件阅读器并用逗号分隔的任何值写入行一样简单。由于您的“警报”是单个字符串，这非常简单：
string desktopFilePath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "RegistroGimb.csv");
StringBuilder output = new();
output.AppendLine("Registro de Actividades"); // Header
output.AppendLine(string.Empty); // blank line
foreach(var line in receivedDataList)
output.AppendLine(line);
File.WriteAllText(desktopFilePath, output.ToString());
这会将输出写入桌面上的 CSV 中。这将在每次运行时覆盖任何现有的 RegistroGimb.csv 文件。您可以检查文件是否存在并使用
AppendAllTextstring desktopFilePath = Path.Combine(Environment.GetFolderPath(Environment.SpecialFolder.Desktop), "RegistroGimb.csv");
StringBuilder output = new();
bool isNewFile = !File.Exists(desktopFilePath);
if (isNewFile)
{ // Add header only if creating a new file.
output.AppendLine("Registro de Actividades"); // Header
output.AppendLine(string.Empty); // blank line
}
foreach(var line in receivedDataList)
output.AppendLine(line);
if (newFile)
File.WriteAllText(desktopFilePath, output.ToString());
else
File.AppendAllText(desktopFilePath, output.ToString());
无需弄乱 Excel 文档。 Excel 将识别并打开 CSV 文件。
