[英]How do I get image properties?
盡管還需要其他屬性,但最重要的屬性是圖像的高度和寬度。
我嘗試了這段代碼:
private void getImageProperties()
{
OpenFileDialog openFileDialog = new OpenFileDialog();
openFileDialog.ShowDialog();
Dictionary<int, KeyValuePair<string, string>> fileProps =
GetFileProps(openFileDialog.FileName);
foreach (KeyValuePair<int, KeyValuePair<string, string>> kv in fileProps)
Console.WriteLine(kv.ToString());
}
但是什么是GetFileProps
? 它不存在。
這是GetFileProps
:
Dictionary<int, KeyValuePair<string, string>> GetFileProps(string filename)
{
Shell shl = new ShellClass();
Folder fldr = shl.NameSpace(Path.GetDirectoryName(filename));
FolderItem itm = fldr.ParseName(Path.GetFileName(filename));
Dictionary<int, KeyValuePair<string, string>> fileProps = new Dictionary<int, KeyValuePair<string, string>>();
for (int i = 0; i < 100; i++)
{
string propValue = fldr.GetDetailsOf(itm, i);
if (propValue != "")
{
fileProps.Add(i, new KeyValuePair<string, string>(fldr.GetDetailsOf(null, i), propValue));
}
}
return fileProps;
}
但這需要添加一些參考。 有關更多信息,請從復制方法的地方查看此論壇 。 並且請開始使用Google!
您可以嘗試一下;
string path = "Path of image";
Bitmap bmp = new Bitmap(path);
StringBuilder sb = new StringBuilder();
FileInfo fi = new FileInfo(path);
sb.AppendLine("Name : " + fi.Name);
sb.AppendLine("Width : " + bmp.Width);
sb.AppendLine("Height : " + bmp.Height);
sb.AppendLine("Horizontal Resolution : " + bmp.HorizontalResolution);
sb.AppendLine("Vertical Resolution : " + bmp.VerticalResolution);
string type = "";
if (fi.Extension == ".bmp")
{
type = "Bitmap Image";
}
else if (fi.Extension == ".jpg" || fi.Extension == ".jpeg")
{
type = "Joint Photographic Experts Group Image File";
}
else if (fi.Extension == ".png")
{
type = "Portable Network Graphic Image";
}
sb.AppendLine("Type : " + type);
bmp.Dispose();
MessageBox.Show(sb.ToString(), path, MessageBoxButtons.OK, MessageBoxIcon.Information);
這適用於任何.bmp,.png,.jpg,.jpeg文件,但您可以添加更多文件,如果需要, 這里是示例項目。
希望能幫助到你。
進行修改以提供更完整的示例:
您在代碼中缺少一個方法。 您可以自己重新創建它。
使用System.Drawing
命名空間:
Dictionary<int, KeyValuePair<string, string>> GetFileProps(string path)
{
System.Drawing.Image image = System.Drawing.Image.FromFile(path);
var dictionary = new Dictionary<int, KeyValuePair<string, string>>();
dictionary.Add(1, new KeyValuePair<string, string>("Width", image.Width.ToString()));
dictionary.Add(2, new KeyValuePair<string, string>("Height", image.Height.ToString()));
//Implement the rest of the properties you deem important here.
return dictionary;
}
