如何在WinForm中的PictureBox中显示文件系统中的图像 [英] How to display an image from file system in a PictureBox in WinForm

问题描述

我对在WinForms中加载PictureBox中的图像有一点疑问。

我想在 PictureBox中显示来自文件系统的图像文件在我的表格上，说 form1 。

I have a small doubt regarding loading an image in PictureBox in WinForms.
I want to show an image file from file system in a PictureBox on my form, say form1.

我正在使用C＃进行Windows应用程序。

I am doing Windows applications using C#.

我想检查文件类型也说是pdf / text / png / gif / jpeg。

是否可以使用C＃以编程方式从文件系统中打开文件？

如果有人知道，请提供任何想法或示例代码。

I want to check the file type also say is it pdf/text/png/gif/jpeg.
Is it possible to programmatically open a file from file system using C#?
If anyone knows please give any idea or sample code for doing this.

修改后的代码：我这样做是为了在我的系统中打开文件，但我不知道如何附加文件并附加文件。

Modified Code: I have done like this for opening a file in my system, but I don't know how to attach the file and attach the file.

 private void button1_Click(object sender, EventArgs e)
 {    
         string filepath = @"D:\";

    openFileDialog1.Filter = "Image Files (*.jpg)|*.jpg|(*.png)|*.png|(*.gif)|*.gif|(*.jpeg)|*.jpeg|";
    openFileDialog1.CheckFileExists = true;
    openFileDialog1.CheckPathExists = true;

    if (openFileDialog1.ShowDialog(this) == DialogResult.OK)
    {
        try 
        {


        }        
    }
 }

我不知道我要写什么尝试阻止。任何人都可以帮忙吗？

I don't know what I have to write in try block. Can anyone help on this?

推荐答案

使用Image.ImageFromFile http://msdn.microsoft.com/en-us/library/system.drawing.image.fromfile.aspx 方法

Use Image.ImageFromFile http://msdn.microsoft.com/en-us/library/system.drawing.image.fromfile.aspx method

图片img = Image.ImageFromFile（openFileDialog1.FileName）;

Image img = Image.ImageFromFile(openFileDialog1.FileName);

应该有效。

编辑

如果你打算将它设置为PictureBox，那么看什么在里面完成，使用picturebox

If you're going to set it to PictureBox, and what to see complete inside it, use picturebox

SizeMode 属性。
