Question

获取异常IndexOutOfRangeException 我怎么解决呢？是什么原因造成的？

public partial class Form1 : Form
{
   const int PROCESS_WM_READ = 0x0010;

   [DllImport("kernel32.dll")]
   public static extern IntPtr OpenProcess(int dwDesiredAccess, bool bInheritHandle, int dwProcessId);

   [DllImport("kernel32.dll")]
   public static extern bool ReadProcessMemory(int hProcess,
      int lpBaseAddress, byte[] lpBuffer, int dwSize, ref int lpNumberOfBytesRead);

   public Form1()
   {
      InitializeComponent();

      Process process = Process.GetProcessesByName("notepad")[0];
   }
}

为什么我会收到此异常？

索引超出了数组的范围

那是因为GetProcessesByName没有返回任何结果;索引0没有对象。这意味着它没有找到流程notepad。

我试图通过名称获取进程记事本，但获得异常IndexOutOfRangeException
