Question

我已经创建了一个构造函数类来调用来构建我的列表，但是我收到了一个错误：

错误CS0029：无法隐式转换类型System.Collections.Generic.List<string>' to System.Collections.Generic.List'

我很困惑，因为我认为文件列表是一个字符串。我需要将类型转换为？

// Create Constructor Class
public class ImagePath
{
    public string path;

    public ImagePath (string newPath)
    {
        path = newPath;
    }
}

public class LoadGalleryList : MonoBehaviour
{       
    void Start()
    {
        // Call ImagePath Constructor Class to build Lists
        List<ImagePath> arctopithecusImageList = Directory.GetFiles(@"/Users/kenmarold/Screenshots/ARCTOPITHECUS/", "*.jpg").ToList();
        List<ImagePath> arctopithecusPNGImageList = Directory.GetFiles(@"/Users/kenmarold/Screenshots/ARCTOPITHECUS/", "*.jpg").ToList();
        List<ImagePath> gulonImageList = Directory.GetFiles(@"/Users/kenmarold/Screenshots/ARCTOPITHECUS/", "*.jpg").ToList();
        List<ImagePath> scythianWolfImageList = Directory.GetFiles(@"/Users/kenmarold/Screenshots/ARCTOPITHECUS/", "*.jpg").ToList();
        List<ImagePath> simivulpaImageList = Directory.GetFiles(@"/Users/kenmarold/Screenshots/ARCTOPITHECUS/", "*.jpg").ToList();
        List<ImagePath> succorathImageList = Directory.GetFiles(@"/Users/kenmarold/Screenshots/ARCTOPITHECUS/", "*.jpg").ToList();
        List<ImagePath> tatusImageList = Directory.GetFiles(@"/Users/kenmarold/Screenshots/ARCTOPITHECUS/", "*.jpg").ToList();
    }
}

Answer 1

GetFiles().ToList()会返回List<string>，您要将其存储在List<ImagePath>对象中。您需要将List<string>中的每个元素转换为ImagePath。

LINQ可以解决您的问题：

List<ImagePath> imagePathList =
    Directory.GetFiles(directoryPath).Select(f => new ImagePath(f)).ToList();

使用ToString构建文件路径列表
