C# 编辑后如何关闭文本文件?
我在C# 编辑后如何关闭文本文件?,c#,visual-studio-2012,C#,Visual Studio 2012,我在表单应用程序中有一个文本文件installer\u input.txt和一个checkedListBox2。如果在checkesListBox2中有一些更改,我想编辑文本文件。我有两部分代码,我知道它们很长,但我需要一些帮助: private void checkedListBox2_SelectedIndexChanged(object sender, EventArgs e) { string path = AppDomain.CurrentDo
表单应用程序中有一个文本文件installer\u input.txt
和一个checkedListBox2
。如果在checkesListBox2
中有一些更改,我想编辑文本文件。我有两部分代码,我知道它们很长,但我需要一些帮助:
private void checkedListBox2_SelectedIndexChanged(object sender, EventArgs e)
{
string path = AppDomain.CurrentDomain.BaseDirectory.ToString();
var lin = (path + "config.ini").ToString();
var lines = File.ReadAllLines(lin);
string InstallerFile = lines.Where(txt => txt.Contains("IstallerFile="))
.Select(txt => txt.Split('=')[1].Replace("\"", "")).FirstOrDefault();
string pathTemp = @"C:\temp\";
string[] pathArr = InstallerFile.Split('\\');
string[] fileArr = pathArr.Last().Split('\\');
string fileArr1 = String.Join(" ", fileArr);
string installerfilename = string.Format("{0}{1}", pathTemp, fileArr1);
IEnumerable<string> inilines = File.ReadAllLines(installerfilename).AsEnumerable();
bool IsChecked = checkedListBox2.CheckedItems.Contains(checkedListBox2.SelectedItem);
else if (fileArr1.Equals("installer_input.txt"))
{
if (IsChecked && checkedListBox2.CheckedItems.Count != checkedListBox2.Items.Count)
inilines = inilines.Select(line => line == string.Format("#product.{0}", checkedListBox2.SelectedItem)
? Regex.Replace(line, string.Format("#product.{0}", checkedListBox2.SelectedItem), string.Format(@"product.{0}", checkedListBox2.SelectedItem))
: line);
else if (!IsChecked || checkedListBox2.CheckedItems.Count == checkedListBox2.Items.Count)
inilines = inilines.Select(line => (line == string.Format("product.{0}", checkedListBox2.SelectedItem))
? Regex.Replace(line, string.Format(@".*product.{0}", checkedListBox2.SelectedItem), string.Format(@"#product.{0}", checkedListBox2.SelectedItem))
: line);
if (checkedListBox2.CheckedItems.Count == checkedListBox2.Items.Count)
checkBox1.Checked = true;
else
checkBox1.Checked = false;
string strWrite = string.Join(Environment.NewLine, inilines.ToArray());
File.WriteAllText(installerfilename, strWrite);
}
}
private void checkedListBox2\u SelectedIndexChanged(对象发送方,事件参数e)
{
字符串路径=AppDomain.CurrentDomain.BaseDirectory.ToString();
var lin=(path+“config.ini”).ToString();
var lines=File.ReadAllLines(lin);
string InstallerFile=行。其中(txt=>txt.Contains(“IstallerFile=”))
.Select(txt=>txt.Split('=')[1]。替换(“\”,”).FirstOrDefault();
字符串pathTemp=@“C:\temp\”;
string[]pathArr=InstallerFile.Split('\\');
字符串[]fileArr=pathArr.Last().Split('\\');
string fileArr1=string.Join(“,fileArr);
string installerfilename=string.Format(“{0}{1}”,pathTemp,fileArr1);
IEnumerable inilines=File.ReadAllLines(installerfilename).AsEnumerable();
bool IsChecked=checkedListBox2.CheckedItems.Contains(checkedListBox2.SelectedItem);
else if(fileArr1.Equals(“installer\u input.txt”))
{
if(IsChecked&&checkedListBox2.CheckedItems.Count!=checkedListBox2.Items.Count)
inilines=inilines.Select(line=>line==string.Format(“#product.{0}”),选中ListBox2.SelectedItem)
?Regex.Replace(line,string.Format(“#product.{0}”,checkedListBox2.SelectedItem),string.Format(@“product.{0}”,checkedListBox2.SelectedItem))
:行);
如果(!IsChecked | | checkedListBox2.CheckedItems.Count==checkedListBox2.Items.Count),则为else
inilines=inilines.Select(line=>(line==string.Format(“product.{0}”,checkedListBox2.SelectedItem))
?Regex.Replace(line,string.Format(@“.*product.{0}”,checkedListBox2.SelectedItem),string.Format(@“#product.{0}”,checkedListBox2.SelectedItem))
:行);
if(checkedListBox2.CheckedItems.Count==checkedListBox2.Items.Count)
checkBox1.Checked=true;
其他的
checkBox1.Checked=false;
string strWrite=string.Join(Environment.NewLine,inilines.ToArray());
WriteAllText(installerfilename,strWrite);
}
}
第二个代码是:
private void checkBox1_CheckedChanged_1(object sender, EventArgs e)
{
CheckBox cb = sender as CheckBox;
SetAllItemsChecked(cb.Checked);
var installerLines = ReadInstallerLines();
SetAllProductsChecked(installerLines.ToList(), cb.Checked);
SaveInstaller(installerLines);
}
private void SetAllItemsChecked(bool check)
{
for (int i = 0; i < this.checkedListBox2.Items.Count; i++)
{
this.checkedListBox2.SetItemChecked(i, check);
}
}
private IEnumerable<string> ReadInstallerLines()
{
var lin = (path + "config.ini").ToString();
var lines = File.ReadAllLines(lin);
string InstallerFile = lines.Where(txt => txt.Contains("IstallerFile="))
.Select(txt => txt.Split('=')[1].Replace("\"", "")).FirstOrDefault();
string pathTemp = @"C:\temp\";
string[] pathArr = InstallerFile.Split('\\');
string[] fileArr = pathArr.Last().Split('\\');
string fileArr1 = String.Join(" ", fileArr);
string installerfilename = pathTemp + fileArr1;
string installertext = File.ReadAllText(installerfilename);
return File.ReadLines(pathTemp + fileArr1);
}
private void SetAllProductsChecked(IList<string> installerLines, bool check)
{
for (var i = 0; i < installerLines.Count; i++)
{
if (installerLines[i].Contains("product="))
{
installerLines[i] = check
? installerLines[i].Replace("#product", "product")
: installerLines[i].Replace("product", "#product");
}
if (installerLines[i].Contains("product."))
{
installerLines[i] = check
?installerLines[i].Replace("#product.", "product.")
: installerLines[i].Replace("product.", "#product.");
}
}
}
private void SaveInstaller(IEnumerable<string> installerLines)
{
var lin = (path + "config.ini").ToString();
var lines = File.ReadAllLines(lin);
string InstallerFile = lines.Where(txt => txt.Contains("IstallerFile="))
.Select(txt => txt.Split('=')[1].Replace("\"", "")).FirstOrDefault();
string pathTemp = @"C:\temp\";
string[] pathArr = InstallerFile.Split('\\');
string[] fileArr = pathArr.Last().Split('\\');
string fileArr1 = String.Join(" ", fileArr);
string installerfilename = pathTemp + fileArr1;
File.WriteAllLines(installerfilename, installerLines);
}
}
private void checkBox1\u CheckedChanged\u 1(对象发送方,事件参数e)
{
复选框cb=发送方作为复选框;
SetAllItemsChecked(cb.已检查);
var installerLines=ReadInstallerLines();
SetAllProductsChecked(installerLines.ToList(),cb.Checked);
SaveInstaller(installerLines);
}
私有无效设置项已检查(布尔检查)
{
对于(int i=0;itxt.Contains(“IstallerFile=”))
.Select(txt=>txt.Split('=')[1]。替换(“\”,”).FirstOrDefault();
字符串pathTemp=@“C:\temp\”;
string[]pathArr=InstallerFile.Split('\\');
字符串[]fileArr=pathArr.Last().Split('\\');
string fileArr1=string.Join(“,fileArr);
字符串installerfilename=pathTemp+fileArr1;
string installertext=File.ReadAllText(installerfilename);
返回File.ReadLines(pathTemp+fileArr1);
}
私有void SetAllProductsChecked(IList安装线,布尔检查)
{
对于(var i=0;itxt.Contains(“IstallerFile=”))
.Select(txt=>txt.Split('=')[1]。替换(“\”,”).FirstOrDefault();
字符串pathTemp=@“C:\temp\”;
string[]pathArr=InstallerFile.Split('\\');
字符串[]fileArr=pathArr.Last().Split('\\');
string fileArr1=string.Join(“,fileArr);
字符串installerfilename=pathTemp+fileArr1;
writeAllines(installerfilename,installerLines);
}
}
首先,我可以选中列表中的复选框,但当我尝试单击复选框1时,我出现了下一个错误:进程无法访问文件“C:\temp\installer\u input.txt”,因为它被另一个进程使用。
如何使程序工作?如何优化代码?基本上,一个线程/进程可以访问一个资源,在本例中,该资源就是一个实例中的文件
EventWaitHandle waitHandle = new EventWaitHandle(true, EventResetMode.AutoReset, "SHARED_BY_ALL_PROCESSES");
waitHandle.WaitOne();
/* process file*/
waitHandle.Set();
