我需要让我的代码在文件不存在时创建文件,否则追加内容。目前的代码是:如果文件存在,则创建并追加内容。以下是代码:
if (File.Exists(path))
{
using (StreamWriter sw = File.CreateText(path))
{
我应该这样做吗?
if (! File.Exists(path))
{
using (StreamWriter sw = File.CreateText(path))
{
编辑:
string path = txtFilePath.Text;
if (!File.Exists(path))
{
using (StreamWriter sw = File.CreateText(path))
{
foreach (var line in employeeList.Items)
{
sw.WriteLine(((Employee)line).FirstName);
sw.WriteLine(((Employee)line).LastName);
sw.WriteLine(((Employee)line).JobTitle);
}
}
}
else
{
StreamWriter sw = File.AppendText(path);
foreach (var line in employeeList.Items)
{
sw.WriteLine(((Employee)line).FirstName);
sw.WriteLine(((Employee)line).LastName);
sw.WriteLine(((Employee)line).JobTitle);
}
sw.Close();
}
}
