图像保存路径,导致运行时错误
本文关键字:运行时错误 保存 路径 图像 | 更新日期: 2023-09-27 18:36:10
每当我尝试自动保存网络摄像头捕获图像时,都会出现运行时错误,然后 path.automaticaly 名称如 0.jpg,02.jpg,03.jpg这样图像将保存在特定的提及文件夹中,但给出运行时错误。请检查此内容。
namespace camera1
{
public partial class Form1 : Form
{
private Capture capture;
private bool captureinprogress;
public Form1()
{
InitializeComponent();
}
private void ProcessFrame(object sender, EventArgs arg)
{
Image<Bgr, Byte> ImageFrame = capture.QueryFrame();
cameraimage.Image = ImageFrame;
string root = "C:''photo'0"; // automatically saving image to c drive like 001.jpg,002.jpg;
for (int i = 0; i < 100; i++)
{
if (File.Exists(" "))
{ }
else
{
string Path = root + i + ".jpg";
ImageFrame.Save(Path);
}
{
if (ImageFrame != null)
{
pictureBox1.Image = ImageFrame.ToBitmap();
}
if (pictureBox1 != null)
{
pictureBox2.Image = ImageFrame.ToBitmap();
}
if (pictureBox2 != null)
{
pictureBox3.Image = ImageFrame.ToBitmap();
}
}
}
}
private void btnStart_Click(object sender, EventArgs e)
{
if (capture == null)
{
try
{
capture = new Capture();
}
catch (NullReferenceException excpt)
{
MessageBox.Show(excpt.Message);
}
}
if (capture != null)
{
if (captureinprogress)
{ //if camera is getting frames then stop the capture and set button Text
// "Start" for resuming capture
btnstart.Text = "Start!"; //
Application.Idle -= ProcessFrame;
}
else
{
//if camera is NOT getting frames then start the capture and set button
// Text to "Stop" for pausing capture
btnstart.Text = "Stop";
Application.Idle += ProcessFrame;
}
captureinprogress = !captureinprogress;
}
}
private void ReleaseData()
{
if (capture != null)
capture.Dispose();
}
}
}
你需要屏蔽反斜杠,否则编译器会尝试解释'p
oder '0
,这是他不能
因此,实现此目的的最简单方法是在字符串的开头添加一个@
。
string root = @"C:'photo'0";
或者您一直使用双反斜杠:
string root = "C:''photo''0";
如需进一步参考,请阅读:

包含反斜杠的路径字符串的无法识别的转义序列

我这里没有实例,但您需要将其更改为
string root = @"C:'photo'0'";// instead of string root = "C:''photo'0";
注意:您无法直接保存到 C: 云端硬盘中,因为您需要以管理权限运行程序。我建议使用桌面上的文件夹或某些库文件夹,例如"我的图片"。
