C# 利用浏览按钮获得 文件路径 和 文件夹路径

生成文件路径

private void btnChoose_Click(object sender, EventArgs e)

        {
            using (OpenFileDialog dialog = new OpenFileDialog())
            {
                dialog.Multiselect = true;
                if (dialog.ShowDialog() == DialogResult.OK)
                {
                    try
                    {
                        this.tbFilePath.Text = dialog.FileName;
                    }
                    catch(Exception ex)
                    {
                        throw(ex);
                    }
                }
            }

生成文件夹路径

新建一个FolderDialog类（重载FolderNameEditor）

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using System.Windows.Forms.Design;
using System.Windows.Forms;

namespace   Common
{
    class FolderDialog:FolderNameEditor
    {
        FolderBrowser fDialog = new FolderBrowser();
        public FolderDialog(){ }

        public DialogResult DisplayDialog()
        {
            return DisplayDialog("请选择一个文件夹");
        }

        public DialogResult DisplayDialog(string description)
        {
            fDialog.Description = description;
            return fDialog.ShowDialog();
        }

        public string Path
        {
            get
            {
                return fDialog.DirectoryPath;
            }
        }

        ~FolderDialog()
        {
            fDialog.Dispose();
        }
    }
}

浏览按钮下的事件

private void btnChoose_Click(object sender, EventArgs e)
        {
            FolderDialog fDialog = new FolderDialog();
            fDialog.DisplayDialog();
            this.tbfilePath.Text = fDialog.Path;
        }

更简单的方法：

1. //选择
2.         private void btnUser_Click(object sender, EventArgs e)
3.         {
4.             //选择文件
5.             OpenFileDialog openFileDialog = new OpenFileDialog();
6.             openFileDialog.Multiselect = true;
7.             //文件格式
8.             openFileDialog.Filter = "所有文件|*.*";
9.             //还原当前目录
10.             openFileDialog.RestoreDirectory = true;
11.             //默认的文件格式
12.             openFileDialog.FilterIndex = 1;
13.             if (openFileDialog.ShowDialog() == DialogResult.OK)
14.             {
15.                 string path = openFileDialog.FileName;
16. 
17.             }
18.           
19.             //选择文件夹
20.             FolderBrowserDialog dialog = new FolderBrowserDialog();
21.             dialog.Description = "请选择文件路径";
22.             if (dialog.ShowDialog() == DialogResult.OK)
23.             {
24.                 string foldPath = dialog.SelectedPath;
25.                 MessageBox.Show("已选择文件夹:" + foldPath, "选择文件夹提示", MessageBoxButtons.OK, MessageBoxIcon.Information);
26.             }
27.         }
