public static string? ReadPathFromReg(string subPath, string name) {

调用方式：
ReadPathFromReg(@"SOFTWARE\Tencent\WeChat", "FileSavePath");
用gpt转换为go语言（仅作参考，可能需要修改优化）：
package main
import (
"fmt"
"github.com/Microsoft/Windows-sysinternals-docs/blob/master/registry/goreg"
)
func main() {
subPath := "YourRegistrySubPath"
name := "YourValueName"
value, err := ReadValueFromReg(subPath, name)
if err != nil {
fmt.Println("Error reading from registry:", err)
} else {
fmt.Println("Value read from registry:", value)
}
}
func ReadValueFromReg(subPath, name string) (string, error) {
// First, try to read from LocalMachine hive
key, err := winreg.OpenKey(winreg.HKEY_LOCAL_MACHINE, subPath, winreg.QUERY_VALUE)
if err == nil {
defer key.Close()
value, _, err := key.GetStringValue(name)
if err == nil {
return value, nil
}
}
// If that fails, try to read from CurrentUser hive
key, err = winreg.OpenKey(winreg.HKEY_CURRENT_USER, subPath, winreg.QUERY_VALUE)
if err == nil {
defer key.Close()
value, _, err := key.GetStringValue(name)
if err == nil {
return value, nil
}
}
return "", err
}
