从目录(winforms)加载附件

本文关键字：加载 winforms | 更新日期: 2023-09-27 17:50:01

我有一个类(GeneralSpecVersion)。一个属性是"published"。我想从这个类中获取一个对象，从系统上的已发布文件夹中向该对象添加文件，并加载该文件夹中的文件。由于可以有多个文件，因此该属性返回一个字符串列表。

我有这个"工作"，但这需要我在我的类和winform格式代码中声明文件路径。我想最小化的形式代码，并保持我的逻辑在我的属性。因为我只是习惯使用简单的"get,set"，我甚至不确定我是否正确设置了属性代码。

总之

从类中加载对象，为该对象添加文件名，加载文件

我班上

public partial class GeneralSpecVersion : IEquatable<GeneralSpecVersion>, IComparable<GeneralSpecVersion>, IComparable
{
    ...
    private List<string> _Published;
    public List<string> Published
    {          
        get {
            string path = (Data.Database.Setting.GetApplicationOption("GenSpecAttachments", ""));
            string published = System.IO.Path.Combine(path, Acronym + "''" + Major + "." + Minor + "''Published");
            string invalid = new string(Path.GetInvalidFileNameChars()) + new string(Path.GetInvalidPathChars());
            foreach (char c in invalid)
            {
                Acronym = Acronym.Replace(c.ToString(), "_");
            }
            if (!Directory.Exists(published))
            {
                Directory.CreateDirectory(published);
            }
            return _Published;
        }
        set { _Published = value; }
    }
}

Major和minor是类中的其他属性。

代码片段:

var genSpec = GeneralSpecification.GeneralSpecVersion.DataLoad("ELECTRICAL", "1", "01");
string publishedDir = "C:''NewTest''" 
                    + dgvAcronymSearch.Rows[0].Cells[0].Value.ToString() + "''"
                    + dgvAcronymSearch.Rows[0].Cells[2].Value.ToString() + "." 
                    + dgvAcronymSearch.Rows[0].Cells[3].Value.ToString() + "''Published";
foreach(string filepath in Directory.GetFiles(publishedDir))
{
    string file = Path.GetFileName(filepath);
    genSpec.Published.Add(dgvAcronymSearch.Rows[0].Cells[0].Value.ToString());
    Process.Start(filepath);
}

从目录(winforms)加载附件

代码中有一个bug, Acronym中的特殊字符在合并后被替换，必须在合并前完成

一般来说，在get属性中创建目录不是一个好做法。Get应该能够在没有副作用的情况下被调用。

使用文件夹标签可能是一个值得考虑的方法。例如

private static readonly String PublishedFolderPattern = "<BaseFolder>''<FolderName>''<Major>.<Minor>''Published";
public static String GetPublishedFolder(String FolderName, int Major, int Minor, bool CreateDirectory = false) {
    String BaseFolder = (Data.Database.Setting.GetApplicationOption("GenSpecAttachments", ""));
    return GetPublishedFolder(BaseFolder, FolderName, Major, Minor, CreateDirectory);
}
public static String GetPublishedFolder(String BaseFolder, String FolderName, int Major, int Minor, bool CreateDirectory = false) {
    // needs to come before
    FolderName = FolderName.Trim('''');
    string invalid = new string(Path.GetInvalidFileNameChars()) + new string(Path.GetInvalidPathChars());
    foreach (char c in invalid)
    {
        FolderName = FolderName.Replace(c, '_');
    }
    string published = PublishedFolderPattern;
    published = published.Replace("<BaseFolder>", BaseFolder);
    published = published.Replace("<FolderName>", FolderName);
    published = published.Replace("<Major>", Major.ToString());
    published = published.Replace("<Minor>", Minor.ToString());
    if (CreateDirectory && !Directory.Exists(published))
        Directory.CreateDirectory(published);
    return published;
}
