我有三个按钮标题/正文/页脚.MY标题在行尾有空格1983年然后我的身体开始于1984年,当我首先保存我的身体,同时导出到文本文件它复制很好,但当我点击标题附加文件的一半数据被标题替换为空格。我可以先保存我的身体,然后在附加标题时向下推动身体是可能的。
我的标题:
FileStream fs = new FileStream(@"C:\Users\IT-Administrator\Desktop\ee.txt", FileMode.Open, FileAccess.ReadWrite);
fs.Seek(0, SeekOrigin.Begin);
StreamWriter sw = new StreamWriter(fs);
//sw.WriteLine(comboBox7.Text +comboBox2.Text +textBox6.Text);
sw.WriteLine("{0}{1}{2}{3,-1983}", comboBox7.Text, comboBox2.Text,textBox6.Text, ' ');
sw.Close();
fs.Close();
我的身体按钮:
if (myDataset == null)
{
return;
}
if (myDataset.Tables[0].Rows.Count == 0)
{
return;
}
DataView vwExport = new DataView(myDataset.Tables[0]);
SaveFileDialog sfd = new SaveFileDialog();
sfd.Filter = "TXT file|*.txt";
sfd.FileName = "ticket_info " + ".txt";
if (sfd.ShowDialog() == DialogResult.OK)
{
if (sfd.FileName != "")
{
ExportDatatviewToCsv(sfd.FileName, vwExport);
MessageBox.Show("File has been saved as: " + Environment.NewLine + sfd.FileName + Environment.NewLine + Environment.NewLine + "NB: This dataset has been ordered by t_reference in ascending order. If being combined with an existing dataset - that dataset will also need to be sorted in this way.", "Operation complete", MessageBoxButtons.OK, MessageBoxIcon.Information);
}
}
