当我点击链接标签时,它应该打开一个对话框,可以选择一个JPEG图像文件,然后在另一个表格的图片框中打开。
这是我到目前为止的代码:
private void llblOpenSavedImages_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
OpenFileDialog ofd = new OpenFileDialog();
if (ofd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
Open_Saved_Design_Form frm = new Open_Saved_Design_Form();
frm.Show();
}
}

将图像路径传递给另一个表单构造函数,如下所示:
Open_Saved_Design_Form frm = new Open_Saved_Design_Form();
frm.Show(ofd.FileName);
并在Open_Saved_Design_Form
添加构造函数
private string imgPath;
public Open_Saved_Design_Form(string path)
{
InitializeComponent();
imgPath = path;
}
然后您可以在第二种形式中使用该路径。

您需要将文件名从OpenFileDialog传递到新表单,如下所示:
private void llblOpenSavedImages_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
OpenFileDialog ofd = new OpenFileDialog();
if (ofd.ShowDialog() == System.Windows.Forms.DialogResult.OK)
{
if(!string.IsNullOrEmpty(ofd.FileName))
{
Open_Saved_Design_Form frm = new Open_Saved_Design_Form(ofd.FileName);
frm.Show();
}
}
}
你的第二个表单的构造符应如下所示:
private string fileName;
public Open_Saved_Design_Form(string file)
{
InitializeComponent();
fileName = file;
}
然后在新表单的Load事件中,您将设置图像:
private void Open_Saved_Design_Form_Load(Object sender, EventArgs args)
{
pictureBox.ImageLocation = fileName;
}

表格1:
private void linkLabel1_LinkClicked(object sender, LinkLabelLinkClickedEventArgs e)
{
OpenFileDialog dlg = new OpenFileDialog();
if (dlg.ShowDialog() == DialogResult.OK)
{
if (!string.IsNullOrEmpty(dlg.FileName))
{
Form2 frm = new Form2(dlg.FileName);
frm.Show();
}
}
}
表格2:
private string _imagePath;
public Form2(string imagePath)
{
InitializeComponent();
_imagePath = imagePath;
}
private void Form2_Load(object sender, EventArgs e)
{
pictureBox1.ImageLocation = _imagePath;
}
