为什么我的“；保存“；按钮不起作用
本文关键字：不起作用 按钮 保存 为什么 我的 | 更新日期: 2023-09-27 18:28:26
我有一个程序，它用文本填充文本框。现在我想把文本框中的所有文本保存到一个文件中。
所以我创建了这个：
private void button3_Click(object sender, EventArgs e)
{
timer1.Stop();
saveFileDialog1.ShowDialog();
System.IO.StreamWriter file = new System.IO.StreamWriter("SaveFileDialog1.path");
file.WriteLine(" Time and date:'r'n " + textBox2.Text + "'r'n 'r'n Memory:'r'n " + textBox1.Text + "'r'n " + textBox10.Text + "'r'n " + textBox4.Text + "'r'n " + textBox5.Text + "'r'n 'r'n CPU:'r'n " + textBox6.Text + "'r'n " + textBox11.Text + "'r'n " + textBox12.Text + "'r'n " + textBox13.Text + "'r'n 'r'n Network:'r'n " + textBox7.Text + "'r'n " + textBox3.Text + "'r'n " + textBox8.Text + "'r'n " + textBox9.Text + "'r'n ");
timer1.Start();
}
但当我点击按钮时，我的程序将退出！我不知道为什么。
有人知道为什么或者在代码中看到了错误的部分？

编辑：感谢您的所有回答，但对于所有代码，当savefiledialog1.showdialog（）；线路已运行。我不知道为什么。但其他代码并没有破坏它，只是那一行代码是错误的。对话框不会出现，程序将强制退出。
最终编辑（重要）：谢谢大家帮我写代码。但问题是：没有足够的RAM来加载savefiledialog。当我在没有visual studio的情况下运行.exe时，它运行得很好；-）谢谢大家帮助我！
我不知道计时器是用来做什么的，但这里有更正的代码（传递给StreamWriter的文件名和路径显然不好）：
private void button3_Click(object sender, EventArgs e)
{
timer1.Stop();
if(saveFileDialog1.ShowDialog() == DialogResult.OK)
{
System.IO.StreamWriter file = new System.IO.StreamWriter(saveFileDialog1.FileName);
file.WriteLine(" Time and date:'r'n " + textBox2.Text + "'r'n 'r'n Memory:'r'n " + textBox1.Text + "'r'n " + textBox10.Text + "'r'n " + textBox4.Text + "'r'n " + textBox5.Text + "'r'n 'r'n CPU:'r'n " + textBox6.Text + "'r'n " + textBox11.Text + "'r'n " + textBox12.Text + "'r'n " + textBox13.Text + "'r'n 'r'n Network:'r'n " + textBox7.Text + "'r'n " + textBox3.Text + "'r'n " + textBox8.Text + "'r'n " + textBox9.Text + "'r'n ");
file.Close();
}
timer1.Start();
}
您必须处理文件
file.Dispose();
冲洗并关闭溪流。在调试模式下运行代码以获取信息，目前尚不清楚问题出在哪里。PS：我认为"SaveFileDialog1.path"是一个拼写错误。
//Typically you wrap your streamwriter in a using statement but you can just do this instead.
Stream myStream ;
SaveFileDialog saveFileDialog1 = new SaveFileDialog();
saveFileDialog1.Filter = "txt files (*.txt)|*.txt|All files (*.*)|*.*" ;
saveFileDialog1.FilterIndex = 2 ;
saveFileDialog1.RestoreDirectory = true ;
if(saveFileDialog1.ShowDialog() == DialogResult.OK)
{
if((myStream = saveFileDialog1.OpenFile()) != null)
{
// Code to write the stream goes here.
myStream.Close();
}
}
这样做，因为您的代码需要大量重构，所以我也这样做了。完成。
private void button3_Click(object sender, EventArgs e)
{
try
{
timer1.Stop();
if(saveFileDialog1.ShowDialog()== DialogResult.Ok)
{
using(System.IO.StreamWriter file = new System.IO.StreamWriter(saveFileDialog1.FileName))
{
StringBuilder sb = new StringBuilder(" Time and date:'r'n ");
sb.Append(Environment.NewLine);
sb.Append(textBox2.Text);
sb.Append(Environment.NewLine);
sb.Append(Environment.NewLine);
sb.Append(" Memory:");
sb.Append(Environment.NewLine);
sb.Append(textBox1.Text);
sb.Append(Environment.NewLine);
sb.Append(textBox10.Text);
........
file.WriteLine(sb.ToString());
}
}
timer1.Start();
}
catch(Exception ex)
{
MessageBox.Show(ex.ToString());
}
}
