实现效果:
知识运用:
OpenFileDialog组件的Multiselect属性 //是否允许多选
public bool Multiselect {get;ser;}
FileNames属性 //获取所有选定的文件的文件名
public string[] FileName {get;}
实现代码:
private void button1_Click(object sender, EventArgs e)
{
openFileDialog1.Filter = "txt文件(*.txt)|*.txt";
openFileDialog1.Multiselect = true;
if (openFileDialog1.ShowDialog() == DialogResult.OK)
{
string Content = string.Empty;
foreach(string s in openFileDialog1.FileNames) //注意是s
{
StreamReader sr = new StreamReader(s,Encoding.Default);
Content += sr.ReadToEnd();
sr.Close();
}
textBox1.Text = Content;
}
}
