用C#实现浏览选择文件，并把得到的文件路径显示在文本框里

Answer 1

方法如下，具体代码是：

OpenFileDialog openFileDialog1 = new OpenFileDialog();
            openFileDialog1.Filter = "文档(*.doc;*.docx)|*.doc;*.docx";
            if (openFileDialog1.ShowDialog() == DialogResult.OK)
            {
                if (openFileDialog1.FileName != "")
                {
                    this.textBox3.Text = openFileDialog1.FileName;
                }
            }

Answer 2

private void button2_Click(object sender, EventArgs e)
{
if (textBox1.Text != textBox2.Text)
{
File.Move(textBox1.Text, textBox2.Text);
}
}

private void button1_Click(object sender, EventArgs e)
{
openFileDialog1.ShowDialog();
textBox1.Text = openFileDialog1.FileName;
textBox2.Text = openFileDialog1.FileName;
}

Answer 3

<div>读取文件：<input type="file" onchange="javascript:document.getElementById('iframe').src=this.value; document.getElementById('lujing').innerHTML = this.value;" />
</div>
<div style="color:#000055;">你选择文件的路径为：<div id="lujing" style="color:#000099;"></div>

如果是C#的WinForm程序怎么写呢？

Answer 4

String^ filePath = this->MyOpenFileDialog->FileName
this->MyOpenFileDialog 为C#组件，可以直接拖进来使用
