我在记事本1-5中有这些名单,名称为
情况:当我点击按钮时,名称将逐一显示在richtext中,直到数字结束。我有这个代码但还没有工作。
private void button5_Click(object sender,EventArgs e) {
string file_name = "\\test1.txt";
file_name = textBox1.Text + file_name; //textBox1.Text is my path
int counter = 0;
string line = "";
// Read the file and display it line by line.
StreamReader file = new StreamReader(file_name);
while ((line = file.ReadLine()) != null)
{
richTextBox2.Text = (line);
counter++;
}
file.Close();
// Suspend the screen.
richTextBox2.Text = line; //I use richtext for displaying the output
}

试试这个;
private void button1_Click(object sender, EventArgs e)
{
using (StreamReader sr = File.OpenText("yourPath"))
{
string line;
while ((line = sr.ReadLine()) != null)
{
textBox1.Text = line;
this.Refresh();
Thread.Sleep(1000);
}
}
}
编辑1: 对不起,我为文本框做了。检查一下;
private void button1_Click(object sender, EventArgs e)
{
using (StreamReader sr = File.OpenText("yourPath"))
{
string line;
while ((line = sr.ReadLine()) != null)
{
richTextBox1.Text += line + "\n";
this.Refresh();
Thread.Sleep(1000);
}
}
}

由于您没有指定是否要为WPF或WinForms编写此应用程序,我将假设您使用的是WPF的RichTextbox。这是一个例子:
using (StreamReader sr = new StreamReader("SampleInput.txt"))
{
string line = string.Empty;
while ((line = sr.ReadLine()) != null)
{
rbResult.Document.Blocks.Add(new Paragraph(new Run(line)));
}
}
