Bitmap.save()方法怎么使用
System.IO.Directory.CreateDirectory("C:\\新建文件夹");
string wenjian = "C:\\新建文件夹";
FolderBrowserDialog fbd = new FolderBrowserDialog();
if (fbd.ShowDialog() != DialogResult.OK)
{
return;
}
strpath = fbd.SelectedPath;
strjpg = Directory.GetFiles(strpath, "*.jpg", SearchOption.AllDirectories);
foreach (string jpg in strjpg)
{
System.Drawing.Bitmap objPic, objNewPic;
objPic = new System.Drawing.Bitmap(jpg);
objNewPic = new System.Drawing.Bitmap(objPic, Convert.ToInt32(textBox1.Text), Convert.ToInt32(textBox2.Text));
objNewPic.Save(wenjian + "" + jpg + "");
}
MessageBox.Show("转换成功！");
}

objNewPic.Save(wenjian + "" + jpg + ""); 提示我格式不正确，我如何把转换后的文件放入到一个新的文件夹中？

[解决办法]

C# code

objNewPic.Save(wenjian+"\\"+Path.GetFileName(jpg));
