重载解析失败?

问题描述

这行代码存在一些问题

I am having some problems with this line of code

If RegQueryValueEx(hKey, Value, 0, pdwType, Nothing, pvSize) = ERROR_NONE Then

对于任何了解注册表的人，我想知道如何更正此行，以便它与我的vb.net应用程序一起使用.


函数中未列出的变量是

to anyone with knowledge about the registry I would like to know how to correct this line so that it works with my vb.net application.


the variable not listed in the function is

Private Const ERROR_NONE As Integer = &H0

这里又是一个完整的功能

And here it is once more as a full function

Public Function ValueExists(ByVal RootKey As ROOT_KEY, ByVal SubKey As String, ByVal Value As String) As Boolean
           Dim hKey As UIntPtr = UIntPtr.Zero
           Dim pvSize As UInteger = 0
           Dim pdwType As UInteger = CUInt(VALUE_TYPE.REG_NONE)

           Try
               If RegOpenKeyEx(RootKey, SubKey, 0, KEY_QUERY_VALUE, hKey) <> ERROR_NONE Then
                   Return False
               End If
               Return (RegQueryValueEx(hKey, Value, 0, pdwType, Nothing, pvSize) = ERROR_NONE)
           Finally
               If hKey <> UIntPtr.Zero Then
                   RegCloseKey(hKey)
               End If
           End Try
       End Function

我已将其从C#转换为vb.net，但完整显示错误

错误3重载解析失败，因为对于这些参数，没有可访问的"RegQueryValueEx"是最特定的:
``公共共享函数RegQueryValueEx(hKey作为System.UIntPtr，lpValueName作为字符串，lpReserved作为整数，ByRef lpType作为UInteger，ByRef lpData作为字节，ByRef lpcbData作为UInteger)作为整数'' ``公共共享函数RegQueryValueEx(hKey作为System.UIntPtr，lpValueName作为字符串，lpReserved作为整数，ByRef lpType作为UInteger，lpData作为System.Text.StringBuilder，ByRef lpcbData作为UInteger)作为整数'':并非最具体. C:\ Users \ Admin \ Desktop \ cLightning.vb 1095 24

I have translated this from C# to vb.net but get the error in full

Error3Overload resolution failed because no accessible ''RegQueryValueEx'' is most specific for these arguments:
''Public Shared Function RegQueryValueEx(hKey As System.UIntPtr, lpValueName As String, lpReserved As Integer, ByRef lpType As UInteger, ByRef lpData As Byte, ByRef lpcbData As UInteger) As Integer'': Not most specific.
''Public Shared Function RegQueryValueEx(hKey As System.UIntPtr, lpValueName As String, lpReserved As Integer, ByRef lpType As UInteger, lpData As System.Text.StringBuilder, ByRef lpcbData As UInteger) As Integer'': Not most specific.C:\Users\Admin\Desktop\cLightning.vb109524
