推荐答案

Herez，示例代码读取，递增，然后将DWORD值写入HKEY_CURRENT_USER:

Herez the sample code reads, increments, and then writes a DWORD value to HKEY_CURRENT_USER:

Imports Microsoft.Win32
Dim regVersion As RegistryKey
regVersion =
Registry.CurrentUser.OpenSubKey("SOFTWARE\\Microsoft\\TestApp\\1.0", True)
If regVersion Is Nothing Then
    ' Key doesn't exist; create it.
    regVersion =
Registry.CurrentUser.CreateSubKey("SOFTWARE\\Microsoft\\TestApp\\1.0")
End If

Dim intVersion As Integer = 0
If (Not regVersion Is Nothing) Then
    intVersion = regVersion.GetValue("Version", 0)
    intVersion = intVersion + 1
    regVersion.SetValue("Version", intVersion)
    regVersion.Close()
End If
