Question

我想将图片保存在特定位置。绕过“确认另存为，是否要替换它”弹出窗口。

        private void pictureBox1_Click(object sender, EventArgs e)
        {

        string path = "C:\\MyDocs\\TimeIn&Out\\EmployeesPhoto";
        Directory.CreateDirectory(path);

        saveFileDialog1.InitialDirectory = (@"C:\");
        saveFileDialog1.RestoreDirectory = true;
        saveFileDialog1.Title = "Select Image";
        saveFileDialog1.DefaultExt = ".png";
        saveFileDialog1.Filter = "Image files (*.jpg, *.jpeg, *.jpe, *.jfif, *.png) | *.jpg; *.jpeg; *.jpe; *.jfif; *.png";
        saveFileDialog1.OverwritePrompt = false;

        if(saveFileDialog1.ShowDialog()==DialogResult.OK)
        {
            //path = Path.GetDirectoryName(saveFileDialog1.FileName);
            //pictureBox1.Image.Save(path, System.Drawing.Imaging.ImageFormat.Png);
            // I tried this 2 but not working
        }
    }

在目录中选择图像后点击picturebox1 =＆gt; =＆gt;那么它必须将图像保存在“路径”中。但它显示了这个弹出窗口。

设置属性：

saveFileDialog1.OverwritePrompt = false;

应该阻止覆盖警告。我不知道为什么它不适合你，但你可以使用openFileDialog代替，然后自己保存文件，如果你愿意：

string path = openFileDialog1.FileName;
if (File.Exists(path)){
    File.Delete(path);
}

using (FileStream fs = File.Create(openFileDialog1.FileName)) {
    fs.Write(imageFile, 0, info.Length);
}

编辑因此，您实际上希望允许用户选择图像，然后将图像保存到具有特定名称的特定文件夹中。你的代码没有做任何事情。 SaveFileDialog对话框的目的是保存文件，而不是选择文件。使用OpenFileDialog允许用户选择图像文件，然后自行保存文件。与上面的代码类似，但逻辑不同：

Stream myStream = null;
OpenFileDialog openFileDialog1 = new OpenFileDialog();

openFileDialog1.InitialDirectory = @"c:\" ;
openFileDialog1.RestoreDirectory = true;
openFileDialog1.Title = "Select Image";
openFileDialog1.DefaultExt = ".png";
openFileDialog1.Filter = "Image files (*.jpg, *.jpeg, *.jpe, *.jfif, *.png) | *.jpg; *.jpeg; *.jpe; *.jfif; *.png";

if(openFileDialog1.ShowDialog() == DialogResult.OK) {
    try {
        string path = string path = @"C:\MyDocs\TimeIn&Out\EmployeesPhoto" + browseFileDialog1.FileName;
        if (File.Exists(path)) {
            File.Delete(path);
        }

        if ((myStream = openFileDialog1.OpenFile()) != null) {
            using (myStream) {
                using (var fs = File.Create(browseFileDialog1.FileName)) {
                    myStream.CopyTo(fs);
                }
            }
        }
    }
    catch (Exception ex) {
        MessageBox.Show("Error: Could not read file from disk.");
    }
}

SaveFileDialog选择图像后保存文件（双击）
