datagridview 点击一行数据 显示图片在PictureBox控件中。如何实现。用C#！！ 30
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e){string path=dataGridView1.Rows[dataGridView1.CurrentRow.Index ].Cells["path"].Value.ToString() ;}private void dataGridview1_CellFormatting(object sender, DataGridViewCellFormattingEventArgs e){if (dataGridview1.Columns[e.ColumnIndex].Name.Equals("Image")){string path = e.Value.ToString();e.Value = GetImage(path);}} public System.Drawing.Image GetImage(string path){System.IO.FileStream fs = new System.IO.FileStream(path, System.IO.FileMode.Open);System.Drawing.Image result = System.Drawing.Image.FromStream(fs); fs.Close();
}有什么问题吗？
private void dataGridView1_CellClick(object sender, DataGridViewCellEventArgs e){string path=dataGridView1.Rows[dataGridView1.CurrentRow.Index ].Cells["path"].Value.ToString() ;System.IO.FileStream fs = new System.IO.FileStream(path, System.IO.FileMode.Open);图片控件.Image= System.Drawing.Image.FromStream(fs); fs.Close(); }
若希望程序更健壮，可以给图片读取套上try
那图片的路径是放哪里的？
string path=dataGridView1.Rows[dataGridView1.CurrentRow.Index ].Cells
你的第一行代码取的不是路径吗？
运行有问题
貌似懂了。。是不是要在数据库里加Path的列？在Path列里写图片路径？
的感言：非常感谢！ 相关知识

楼主，你好
有些控件是不符合硬盘的，所以才会出现上面的情况，建议你找一个电脑程序者、帮你解决问题。

出门在外也不愁C#中PictureBox、Timer控件(动态的窗体)
利用PictureBox、Timer控件，做一个动态的窗体。在窗体中有四个picturebox控件，分别实现上下左右四个方向的移动。
(1)窗体设计
（2）代码编写
using System.Collections.G
using System.D
using System.D
using System.L
using System.T
using System.Windows.F
namespace xm4
&&& public
partial class Form1 : Form
public Form1()
&&&&&&&&&&&
InitializeComponent();
private void button1_Click(object sender, EventArgs e)
&&&&&&&&&&&
timer1.Enabled =
private void button2_Click(object sender, EventArgs e)
&&&&&&&&&&&
timer1.Enabled =
private void button3_Click(object sender, EventArgs e)
&&&&&&&&&&&
this.Close();
private void timer1_Tick(object sender, EventArgs e)
&&&&&&&&&&&
if (pictureBox1.Left & this.Width)
&&&&&&&&&&&&&&&
pictureBox1.Left = 0;
&&&&&&&&&&&
&&&&&&&&&&&&&&&
pictureBox1.Left += 5;
&&&&&&&&&&&
if (pictureBox2.Left & 0)
&&&&&&&&&&&&&&&
pictureBox2.Left = W
&&&&&&&&&&&
&&&&&&&&&&&&&&&
pictureBox2.Left -= 5;
&&&&&&&&&&&
if (pictureBox3.Top& this.Bottom)
&&&&&&&&&&&&&&&
pictureBox3.Top = 0;
&&&&&&&&&&&
&&&&&&&&&&&&&&&
pictureBox3.Top += 5;
&&&&&&&&&&&
if (pictureBox4.Top & 0)
&&&&&&&&&&&&&&&
pictureBox4.Top = B
&&&&&&&&&&&
&&&&&&&&&&&&&&&
pictureBox4.Top -= 5;
private void Form1_Load(object sender, EventArgs e)
