我有一个程序，用文本填充文本框。 现在我想将文本框中的所有文本保存到文件中。
所以我创造了这个：
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();
}
但是当我点击按钮时，我的程序将退出！我不知道为什么。
有人知道为什么或在代码中看到错误的部分？

编辑：感谢您的所有答案，但是使用所有代码，程序在savefiledialog1.showdialog（）时崩溃了。线已经运行。我不知道为什么。但其他代码不会崩溃，只是那行代码是错误的。对话框不显示，程序强制退出。
最终编辑（重要）： 谢谢大家帮助我和编写代码。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时工作正常;-)感谢所有人帮助我！

我不知道计时器的用途是什么，但这里有更正的代码（传递给StreamWriter的文件名和路径显然很糟糕）：
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();
}

这样做，因为你的代码需要大量的重构，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());
}
}

您必须处置文件
file.Dispose();
刷新并关闭流。 在调试模式下运行代码以获取信息，不清楚是什么问题。 PS：我认为“SaveFileDialog1.path”是一个错字。
答案 3 :(得分：0)
//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();
}
}
