本文實例講述了C#判斷系統是32位還是64位的方法。分享給大家供大家參考。具體如下：
public static int GetOSBit(){ try { string addressWidth = String.Empty; ConnectionOptions mConnOption = new ConnectionOptions(); ManagementScope mMs = new ManagementScope(@"http://localhost", mConnOption); ObjectQuery mQuery = new ObjectQuery("select AddressWidth from Win32_Processor"); ManagementObjectSearcher mSearcher = new ManagementObjectSearcher(mMs, mQuery); ManagementObjectCollection mObjectCollection = mSearcher.Get(); foreach (ManagementObject mObject in mObjectCollection) { addressWidth = mObject["AddressWidth"].ToString(); } return Int32.Parse(addressWidth); } catch (Exception ex) { return 32; }}這里需要引用System.Management，該方法在以Guest用戶登錄的情況下拋出異常：
或者用以下方法：
[DllImport("kernel32.dll", SetLastError = true, CallingConvention = CallingConvention.Winapi)] [return: MarshalAs(UnmanagedType.Bool)] public static extern bool IsWow64Process([In] IntPtr hProcess, [Out] out bool lpSystemInfo); private static bool Is64Bit() {bool retVal; IsWow64Process( Process.GetCurrentProcess().Handle, out retVal); return retVal; }這里需要引用System.Diagnostics
希望本文所述對大家的C#程序設計有所幫助。
