我正在尝试将一些字符串写入formclosing事件上的文本文件。问题是,Streamwriter不写任何东西,它只是写一个空白的石板。我有两个不同的文本文件,第一个将记录所有图形数据,第二个文本文件将记录与我的应用程序相关的一些偏好。我的代码如下所示的两个关闭事件和一个单独的主力方法:在窗体关闭事件中写入文本文件
private void Form1_FormClosing(object sender, FormClosingEventArgs e)
{
if (e.CloseReason.Equals(CloseReason.WindowsShutDown) || (e.CloseReason.Equals(CloseReason.UserClosing)))
{
if (MessageBox.Show("You are closing this application.\n\nAre you sure you wish to exit ?", "Warning: Not Submitted", MessageBoxButtons.YesNoCancel, MessageBoxIcon.Stop) == DialogResult.Yes)
{
writeContents("Interrupted");
return;
}
else
e.Cancel = true;
}
}
private void writeContents(string status)
{
//---writes the graph data-----
TextWriter twBackupData = new StreamWriter("C://springTestBackupData.txt");
twBackupData.WriteLine("--Cycle#-- --TorqueLower-- --TorqueUpper--");
//writes the table of values in there, assume x and y are the same size arrays
for(int i = 0; i < x.Count; i++)
{
twBackupData.WriteLine(x[i] + " " + y_lower[i] + " " + y_upper[i]);
}
//---writes some of the preferences------
TextWriter twBackupDataInfo = new StreamWriter("C://springTestBackupInfo.txt");
twBackupDataInfo.WriteLine(status);
twBackupDataInfo.WriteLine(cycleCount.ToString());
twBackupDataInfo.WriteLine(section.ToString());
twBackupDataInfo.WriteLine(revsPerCycle.ToString());
twBackupDataInfo.WriteLine(preturns.ToString());
twBackupDataInfo.WriteLine(direction.ToString());
}
如果你能提供建议或帮我找出它为什么写空白我将不胜感激。谢谢!
尝试StreamWriter.Flush(),然后StreamWriter.Close() –
我想'.Close'实际上是调用'.Flush'为好。 –
