Question

C#中怎么用(openFileDialog控件)做出选择一张图片，并把图片赋值给picterBox？

Answer 1

还是代码最实在:
OpenFileDialog dialog = new OpenFileDialog();
//初始化路径为我的图片目录
dialog.InitialDirectory = Environment.GetFolderPath(Environment.SpecialFolder.MyPictures);

if (dialog.ShowDialog() == DialogResult.OK)
{
try
{
pictureBox1.Image = Image.FromFile(dialog.FileName);
}
catch (Exception ex)
{

MessageBox.Show(ex.Message);
}
}

没这麼复杂！看下e我的代码： private void button6_Click(object sender, EventArgs e) { string ImgPath = ""; OpenFileDialog openfiledialog = new OpenFileDialog();。。初始化2openfiledialog对象 openfiledialog。InitialDirectory = "c:";。。设置初始目录 openfiledialog。Filter = "Image Files(*。BMP;*。JPG;*。GIF)|*。BMP;*。JPG;*。GIF|All files (*。*)|*。*"; if (openfiledialog。ShowDialog() == DialogResult。OK) { ImgPath = openfiledialog。FileName; if (File。Exists(ImgPath)) { pictureBox1。ImageLocation = ImgPath; } } } kmgㄦeィpvó┠『’nむiáxvó┠『’

Answer 3

设置openFileDialog 的filter 为：图片文件(*.jpg;*.jpeg;*.gif;*.png)|*.jpg;*.jpeg;*.gif;*.png
filter格式可以根据需要做调整
openFileDialog1_FileOk事件：{ pictureBox1.ImageLocation = openFileDialog1.FileName;}
如果图片需要保存到数据库的话，需要将图片转化为二进制字节码 byte[] bytes = System.IO.File.ReadAllBytes(openFileDialog1.FileName);

Filter里面添加图片的格式 选中之后把路径付给picterBox
