我想從表單窗口瀏覽圖像。我還創建了一個類并創建了一些過濾器。我可以從表格中讀取這張圖片。我的目標是在課堂上宣布它。并在任何地方使用這個圖像。但我不知道我該怎么做。private void btn_BROWSE_Click(object sender, EventArgs e){ OpenFileDialog imge = new OpenFileDialog(); imge.Filter = "Extensions |*.bmp;*.jpg;*.jpeg;*.png;*.tif;*.tiff|" + "BMP|*.bmp|GIF|*.gif|JPG|*.jpg;*.jpeg|PNG|*.png|TIFF|*.tif;*.tiff|" + "Zip Files|*.zip;*.rar"; imge.ShowDialog(); string imgepath = imge.FileName; pBox_SOURCE.ImageLocation = imgepath;//i'm browsing an image}private void sliderKernel_MouseUp(object sender, MouseEventArgs e){ Bitmap OriginalImage = new Bitmap(pBox_SOURCE.Image);} class Filters{ // (i would like to initialize my image in here not in form :) ) }

我將定義一個抽象類 Filter 并將每個過濾器實現為該類的繼承人。
public abstract class Filter
{
public Bitmap Image { get; set; }
public abstract void Apply();
}
一個實現是：
public class SliderKernel : Filter
{
public overrides void Apply()
{
//manipulates the Image property
}
}
如果您想在任何地方使用該圖像，您應該將其聲明為類的靜態成員：
public static class ImageContainer
{
public static Bitmap Image { get; set; }
}
您可以在表單代碼中使用所有這些，如下所示：
private void btn_BROWSE_Click(object sender, EventArgs e)
{
OpenFileDialog imge = new OpenFileDialog();
imge.Filter = "Extensions |*.bmp;*.jpg;*.jpeg;*.png;*.tif;*.tiff|"
+ "BMP|*.bmp|GIF|*.gif|JPG|*.jpg;*.jpeg|PNG|*.png|TIFF|*.tif;*.tiff|"
+ "Zip Files|*.zip;*.rar";
imge.ShowDialog();
string imgepath = imge.FileName;
pBox_SOURCE.ImageLocation = imgepath;//i'm browsing an image
//save the image to the container
ImageContainer.Image = new Bitmap(pBox_SOURCE.Image);
}
private void sliderKernel_MouseUp(object sender, MouseEventArgs e)
{
Filter filter = new SliderKernel () { Image = ImageContainer.Image };
filter.Apply();
}

我認為你應該將圖像轉換為字節數組
使用以下代碼并將其存儲在靜態類中
public byte[] ImageToByteArray(System.Drawing.Image imageIn)
{
using (var ms = new MemoryStream())
{
imageIn.Save(ms,imageIn.RawFormat);
return ms.ToArray();
}
}
https://www.codeproject.com/Articles/15460/C-Image-to-Byte-Array-and-Byte-Array-to-Image-Conv
并使用此代碼轉為圖形顯示在pictureBox中
public Image byteArrayToImage(byte[] byteArrayIn)
{
MemoryStream ms = new MemoryStream(byteArrayIn);
Image returnImage = Image.FromStream(ms);
return returnImage;
}
