我正在尝试在c#中拆分字符串。我收到一个包含多个空格的字符串,我想将其拆分为空格。到目前为止,我所有尝试都失败了。它不会抛出错误,字符串只是保持空白
using System;
using System.Diagnostics;
using System.Management;
[DllImport("user32.dll")]
static extern IntPtr GetForegroundWindow();
[DllImport("user32.dll")]
public static extern IntPtr GetWindowThreadProcessId(IntPtr hWnd, out int ProcessId);
public static Process GetActiveWindowProcess(){
var processWithFocus = GetForegroundWindow();
int processId;
GetWindowThreadProcessId(processWithFocus, out processId);
Process process = Process.GetProcessById(processId);
return process;
}
public static String getCommandLine(){
string wmiQueryString = "SELECT * FROM Win32_Process WHERE ProcessId = " + process.Id;
using (var searcher = new ManagementObjectSearcher(wmiQueryString))
{
using (var results = searcher.Get())
{
ManagementObject mo = results.Cast<ManagementObject>().FirstOrDefault();
if (mo != null)
{
String str = (string)mo["CommandLine"];
Debug.WriteLine(str.Split(' ')); //Splitting the string
return str;
}
}
}
}
我尝试了所有可以找到的方法但结果是一样的。字符串在那里,但字符串数组为空。
var ssizes = myStr.Split(" \t".ToCharArray());
string[] ssize = myStr.Split(null);
string[] ssize = myStr.Split(new char[0]);
//all arrays are emtpy...
我错过了什么吗?
修改 抱歉,错误发生在我的网站上。 Debug不输出Array。我误以为它是空的。
答案 0 :(得分:0)
String.Split()
(无参数)会在所有空格(包括LF / CR)上进行拆分
