如何将图像保存到特定目录 [英] how to save an image to a specific directory

问题描述

我有一个WPF应用程序，其中有一个图像控件，当我点击它时，会显示一个OpenFileDialog，以便从文件中选择一个图像！现在我想将此图像保存到名为working_folder的特定文件夹中



这是我要将图像保存到的文件夹的位置：

 System.IO.Path.GetDirectoryName（System.Reflection.Assembly.GetEntryAssembly（）。Location）+   \\working_folder \\; 

和图像的位置是这个D：\ Users \\ \\ mowglin \图片\ Images，图片类型为.tif

请参阅下面的代码，以便更清楚：

  bool  imgLoaded =  false ; 
 
图片currentImg =（图片）发件人; 
  if （currentImg.Tag！=  null ）
 imgLoaded =（ BOOL ）currentImg.Tag; 
  if （！imgLoaded）
 {
  string  filename = < span class =code-string> ; 
 OpenFileDialog dlg =  new  OpenFileDialog（）; 
 dlg.DefaultExt =  。tif; 
 dlg.Filter =  （* .tif，*。tiff）| * .tif; * .tiff ; 
  bool  result =（ bool ）dlg.ShowDialog（此）; 
  if （result ==  true ）
 {
 filename = dlg.FileName; 
 currentImg.Source =  new  BitmapImage（ new  Uri（filename））; 
  this  .UpdateLayout（）; 
 currentImg.Tag =  true ; 
} 
} 

所以我的问题是，如何将图像保存到specefic目录？

解决方案

尝试currentImg.Save（路径，[你要保存的格式]）;

I have a WPF application where there is an image control and when I click on it, an OpenFileDialog displays in order to choose an image from a file! now I want to save this image to a specific folder called working_folder

this is the location of the folder I want to save the image to:

System.IO.Path.GetDirectoryName(System.Reflection.Assembly.GetEntryAssembly().Location) + "\\working_folder\\";

and the location of the image is this D:\Users\mowglin\Pictures\Images, and the image is type ".tif"
Please see the code below to make this more clear:

bool imgLoaded = false;

            Image currentImg = (Image)sender;
            if (currentImg.Tag != null)
            imgLoaded = (bool)currentImg.Tag;
            if (!imgLoaded)
            {
                string filename = "";
                OpenFileDialog dlg = new OpenFileDialog();
                dlg.DefaultExt = ".tif";
                dlg.Filter = "(*.tif,*.tiff)|*.tif;*.tiff";
                bool result = (bool)dlg.ShowDialog(this);
                if (result == true)
                {
                    filename = dlg.FileName;
                    currentImg.Source = new BitmapImage(new Uri(filename));
                    this.UpdateLayout();
                    currentImg.Tag = true;
                }
            }

so my question is, how can I save the image to a specefic directory?

解决方案

Try currentImg.Save(path,[what format you want to save]);
