使用dailogbox加载图像 [英] loading image using dailogbox

问题描述

我正在尝试使用打开文件对话框将位图图像加载到墨水画布中，而不是通过确定 this code之类的路径来做到这一点? pre lang ="c#"> ImageBrush ib = 新 ImageBrush(); ib.ImageSource = 新 BitmapImage(新 Uri( @" E:\ ss.jpg"，UriKind.Relative))； myInkCanvas.Background = ib;

解决方案

好吧，它始终在 // 创建实例 OpenFileDialog fileOpener = 新 OpenFileDialog(); // 设置属性.. // 仅选择一个文件 fileOpener.MultiSelect = false ; // 显示对话框，返回可为空的布尔值 布尔?结果= openFileDialog1.ShowDialog(); 如果(结果== 真){ 选中// 文件，检查并使用该文件 // 在您的应用程序中. }

Hi,I''m trying to loade a bitmap image into inkcanvas using open file dialog , not by determine the path like this code how can do this ?

ImageBrush ib = new ImageBrush();
           ib.ImageSource = new BitmapImage(new Uri(@"E:\ss.jpg", UriKind.Relative));
           myInkCanvas.Background = ib;

解决方案

Well it was always available on MSDN[^]. Didn''t you look on MSDN to find an answer to the problem?

Look into the documentation and check how can you get the user to be able to get a file selected from the File System using the OpenFileDialog.

Example code for this would like as below,

// create instance
OpenFileDialog fileOpener = new OpenFileDialog();

// set properties..
// select only one file
fileOpener.MultiSelect = false;

// show the dialog, returns nullable bool value
bool? result = openFileDialog1.ShowDialog();
if(result == true) {
   // file selected, check for the file and use it 
   // in your application.
}
