// grep [/h|/H] - Usage Help
//
// grep [/c] [/i] [/l] [/n] [/r] /E:reg_exp /F:files
//
// /c - print a count of matching lines for each input file;
// /i - ignore case in pattern;
// /l - print just files (scanning will stop on first match);
// /n - prefix each line of output with line number;
// /r - recursive search in subdirectories;
//
// /E:reg_exp - the Regular Expression used as search pattern. The Regular Expression can be delimited by
// quotes like "..." and '...' if you want to include in it leading or trailing blanks;
//
// /F:files - the list of input files. The files can be separated by commas as in /F:file1,file2,file3
//and wildcards can be used for their specification as in /F:*file?.txt;
//
//Example:
//
// grep /c /n /r /E:" C Sharp " /F:*.cs

59.弹出快捷菜单
//在工具箱中找到ContextMenuStrip控件，并拖放至Form1窗体
//设计菜单内容
//将contextMenuStrip1与窗体关联。方法是先选定Form1，为其ContextMenuStrip属性设置属性值为contextMenuStrip1
60.文件夹复制到整合操作
FolderDialog aa =
new FolderDialog();
aa.DisplayDialog();
if (aa.Path !=
"")
{
string path = (aa.Path.LastIndexOf(
"\") == aa.Path.Length - 1) ? aa.Path : aa.Path+"\
";
string parent = Path.GetDirectoryName(%%
1);
Directory.CreateDirectory(path + Path.GetFileName(%%
1));
%%
1 = (%%
1.LastIndexOf(
"\") == %%1.Length - 1) ? %%1 : %%1 + "\
";
DirectoryInfo dir =
new DirectoryInfo(%%
1);
FileSystemInfo[] fileArr =
dir.GetFileSystemInfos();
Queue<FileSystemInfo> Folders =
new Queue<FileSystemInfo>
(dir.GetFileSystemInfos());
while (Folders.Count>
0)
{
FileSystemInfo tmp =
Folders.Dequeue();
FileInfo f = tmp
as FileInfo;
if (f ==
null)
{
DirectoryInfo d = tmp
as DirectoryInfo;
Directory.CreateDirectory(d.FullName.Replace((parent.LastIndexOf("\") == parent.Length - 1) ? parent : parent + "\
", path));
foreach (FileSystemInfo fi
in d.GetFileSystemInfos())
{
Folders.Enqueue(fi);
}
}
else
{
f.CopyTo(f.FullName.Replace(parent, path));
}
}
}
