从wpf中的本地计算机下载PDF文件

Answer 1

试试这个我觉得这就是你需要的东西c＃

File.Copy("Path to Local File","Path where you want to download file");

EG

File.Copy("C://test.txt","D://test.txt");

如果你只是想打开一个文件

OpenFileDialog openFileDialog1 = new OpenFileDialog();

openFileDialog1.InitialDirectory = @"C:\";
openFileDialog1.Title = "Browse Files";
openFileDialog1.CheckFileExists = true;

openFileDialog1.CheckPathExists = true;
openFileDialog1.RestoreDirectory = true;

if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
    //Do you operation here
}
