Question

我无法从项目目录导入。这是我的代码：

FileDialog file = new OpenFileDialog();
file.InitialDirectory = @"";
file.Filter = "txt files (*.txt)|*.txt";
file.RestoreDirectory = true;
if (file.ShowDialog() == DialogResult.OK && this.mAT != null)
{
    if (file.FileName != String.Empty || file.FileName != null) 
    return this.mAT.importFromLexiconFile(file.FileName);
}
else return false;
return false;

如何使用目录作为something.txt等文本从本地目录导入文件，而不是在FileDialog中查找文件？

您可以使用以下命令获取项目开始的目录：

Environment.CurrentDirectory;

或者，您可以使用以下内容获取.exe所在的位置：

Path.GetDirectoryName(System.Reflection.Assembly.GetEntryAssembly().Location);

在运行时，这将是：

C：\项目\ MyApplication的\ myproject的\ BIN \调试\

以下是如何找到您的文件，以及您可以使用它做的一些不同的事情。不确定你想要做什么：

private static void Main()
{
    // The directory to search for the file
    var searchPath = Path.GetDirectoryName(
        System.Reflection.Assembly.GetEntryAssembly().Location);

    // The name of the file we're searching for
    var fileName = "MyFile.txt";

    // Get the first match
    var theFile = Directory.GetFiles(searchPath, fileName).FirstOrDefault();

    // If the match is not null, we found the file
    if (theFile != null)
    {
        // Output some information about the file
        Console.WriteLine("Found the file: {0}", fileName);
        Console.WriteLine("The full path of the file is: {0}", theFile);

        // If it's a text file, here's one way to get the contents
        var fileContents = File.ReadAllText(theFile);

        Console.WriteLine("The contents of the file are:{0}{1}", Environment.NewLine, 
            fileContents);

        // If you need detailed info about the file, or 
        // want to write to it, create a FileInfo object
        var fileInfo = new FileInfo(theFile);

        // Output some detailed information about the file
        Console.WriteLine("The file was created on: {0}", fileInfo.CreationTime);
        Console.WriteLine("The file was last modified on: {0}", 
            fileInfo.LastWriteTime);
        Console.WriteLine("The file attributes are:");
        Console.WriteLine(" - ReadOnly: {0}", 
            Convert.ToBoolean(fileInfo.Attributes & FileAttributes.ReadOnly));
        Console.WriteLine(" - Hidden: {0}", 
            Convert.ToBoolean(fileInfo.Attributes & FileAttributes.Hidden));
        Console.WriteLine(" - System: {0}", 
            Convert.ToBoolean(fileInfo.Attributes & FileAttributes.System));
    }
}
