如何在c#中将Spire.Xls.Collections.PicturesCollection放入字符串构建器？

using Spire.Xls;

StringBuilder stringBuilder = new StringBuilder();

foreach (Picture picture in picturesCollection)
{
    // 获取图片的一些属性，例如名称、路径、宽度、高度等
    string name = picture.Name;
    string path = picture.Path;
    int width = picture.Width;
    int height = picture.Height;

    // 将图片信息添加到字符串构建器中
    stringBuilder.AppendLine($"Name: {name}");
    stringBuilder.AppendLine($"Path: {path}");
    stringBuilder.AppendLine($"Width: {width}");
    stringBuilder.AppendLine($"Height: {height}");
}

string result = stringBuilder.ToString();
Console.WriteLine(result);
