导出具体的一个key的代码
public void Export(StringBuilder sb, RegistryKey key)
{
//log down itself.
sb.AppendFormat(CultureInfo.CurrentCulture, "\r\n[{0}]\r\n", key.Name);
//log down values
string[] s = key.GetValueNames();
Array.Sort(s);
//log down "Default" first
try
{
key.GetValue(Default);
ExportValue(sb, key, Default);
}
catch
{
}
foreach(string name in s)
{
if (!name.Equals(Default))
{
ExportValue(sb, key, name);
}
}
//log down subkeys
s = key.GetSubKeyNames();
Array.Sort(s);
foreach(string subKeyName in s)
{
Export(sb, key.OpenSubKey(subKeyName));
}
}
导出Key时先导出其自身，然后导出Key下的所有Values，导出Value时如果有Default Value的话先导出Default Value，然后导出其他Value。导出Value后再递归导出所有的SubKeys。
导出Value的代码
private void ExportValue(StringBuilder sb, RegistryKey key, string name)
{
switch (key.GetValueKind(name))
{
case RegistryValueKind.DWord:
int dword = (int)key.GetValue(name);
if (name.Equals(Default))
{
sb.AppendFormat(CultureInfo.CurrentCulture, "@=dword:{0:X8}\r\n", dword);
}
else
{
sb.AppendFormat(CultureInfo.CurrentCulture, "\"{0}\"=dword:{1:X8}\r\n", name, dword);
}
break;
case RegistryValueKind.String:
if (name.Equals(Default))
{
sb.AppendFormat(CultureInfo.CurrentCulture, "@=\"{0}\"\r\n", key.GetValue(name));
}
else
{
sb.AppendFormat(CultureInfo.CurrentCulture, "\"{0}\"=\"{1}\"\r\n", name, key.GetValue(name));
}
break;
case RegistryValueKind.MultiString:
string[] values = (string[])key.GetValue(name);
if (name.Equals(Default))
{
sb.Append("@=multi_sz:");
}
else
{
sb.AppendFormat(CultureInfo.CurrentCulture, "\"{0}\"=multi_sz:", name);
}
for (int i = 0; i < values.Length; i++)
{
if (i != 0)
{
sb.Append(",");
}
sb.AppendFormat(CultureInfo.CurrentCulture, "\"{0}\"", values[i]);
}
sb.Append("\r\n");
break;
case RegistryValueKind.Binary:
byte[] bytes = (byte[])key.GetValue(name);
if (name.Equals(Default))
{
sb.Append("@=hex:");
}
else
{
sb.AppendFormat(CultureInfo.CurrentCulture, "\"{0}\"=hex:", name);
}
int j = 0;
for (int i = 0; i < bytes.Length; i++)
{
// Display each byte as two hexadecimal digits.
if (i == (bytes.Length - 1))
{
sb.AppendFormat(CultureInfo.CurrentCulture, "{0:X2}", bytes[i]);
}
else
{
sb.AppendFormat(CultureInfo.CurrentCulture, "{0:X2},", bytes[i]);
}
++j;
if (j == 25)
{
j = 0;
sb.Append("\\\r\n");
}
}
sb.Append("\r\n");
break;
}
}
由于Value有不同的数据类型，导出的时候根据数据类型来导出不同的格式。key.GetValueKind()函数可以取出Key数据类型RegistryValueKind。
