如何：在运行时设置图片

使用 Image 类的 FromFile 方法设置 Image 属性。

在下例中，为图像位置设置的路径是 My Documents 文件夹。这样做是出于一个假定，即假定大多数运行 Windows 操作系统的计算机都包含此目录。这还使得具有最低系统访问级别的用户能够安全运行应用程序。以下示例假定窗体已添加控件 PictureBox。

Private Sub LoadNewPict() ' You should replace the bold image ' in the sample below with an icon of your own choosing. PictureBox1.Image = Image.FromFile _ (System.Environment.GetFolderPath _ (System.Environment.SpecialFolder.Personal) _ & "\Image.gif") End Sub private void LoadNewPict(){ // You should replace the bold image // in the sample below with an icon of your own choosing. // Note the escape character used (@) when specifying the path. pictureBox1.Image = Image.FromFile (System.Environment.GetFolderPath (System.Environment.SpecialFolder.Personal) + @"\Image.gif"); } private: void LoadNewPict() { // You should replace the bold image // in the sample below with an icon of your own choosing. pictureBox1->Image = Image::FromFile(String::Concat( System::Environment::GetFolderPath( System::Environment::SpecialFolder::Personal), "\\Image.gif")); }
