如何将一些c#代码转换为Pascal
本文关键字:代码 转换 Pascal | 更新日期: 2023-09-27 18:05:30
我有几个函数,我需要转换成Pascal,包括在我的inno安装程序中,以验证安装时的序列号。
任何帮助将是感激的,因为我没有写任何pascal在大约8年。
下面是c#代码。
public static long DecodeAuthID(String keyset, String toDecode)
{
StringBuilder retval = new StringBuilder();
for (int i = 0; i < toDecode.Length; i++)
{
char[] toDecodeCharArray = toDecode.ToCharArray();
retval.Append(keyset.IndexOf(toDecodeCharArray[i]));
}
return Int32.Parse(retval.ToString());
}
public static string ReverseString(string stringToReverse)
{
char[] values = stringToReverse.ToCharArray();
Array.Reverse(values);
return new string(values);
}
private static void GetLocationFromAuthenticationID()
{
// Get Authentication Key from the Registry
string registryValue = GetAuthIDFromRegistry();
// Decode the Authentication Key to get the location
string value1 = ReverseString(registryValue);
string value2 = value1.Substring(0, 12);
string keyset = ReverseString(value2);
string valuesReversed = value1.Substring(12, value1.Length - 12);
string values = ReverseString(valuesReversed);
// Decode the AuthID
string authID = DecodeAuthID(keyset, values).ToString();
// Convert to Location ID
int locationID = Int32.Parse(authID) - (Int32.Parse(authID) - 1);
}
你可以看看这个(未经测试的,如果我用GetAuthIDFromRegistry
注释掉未实现的行,它就会编译——无法测试,因为我没有任何样本输入/输出数据来处理你的问题)。它可能不是百分之百正确,但至少应该让你从正确的方向开始。
function DecodeAuthID(KeySet: string; toDecode: string): longint;
var
idx, c: Integer;
Temp: string;
begin
Temp := '';
for idx := 1 to Length(toDecode) do
begin
// Replaces keyset.IndexOf. Handles no match found in KeySet just in case.
c := Pos(toDecode[idx], KeySet);
if c > 0 then
Temp := Temp + KeySet[c];
end;
// Handles no values set in result by returning 0
Result := StrToIntDef(Temp, 0);
end;
function ReverseString(stringToReverse: string): string;
var
i: Integer;
begin
Result := '';
for i := 1 to Length(stringToReverse) do
Result := stringToReverse[i] + Result;
end;
procedure GetLocationFromAuthenticationID;
var
registryValue: string;
value1, value2, keyset: string;
valuesReversed: string;
values: string;
authID: LongInt;
locationID: Integer;
begin
// GetAuthIDFromRegistry code not provided in question.
// See InnoSetup Help File, Pascal Scripting: Support Functions Reference,
// subheading "Registry functions"
registryValue := GetAuthIDFromRegistry;
value1 := ReverseString(registryValue);
// Delphi strings are 1 based, as opposed to the C# char array's 0 base
value2 := Copy(value1, 1, 12);
keyset := ReverseString(value2);
valuesReversed := Copy(Value1, 13, Length(value1) - 12);
values := ReverseString(valuesReversed);
authID := DecodeAuthID(keyset, values);
locationID := authID - (authID - 1);
end;
这里所有不包含源代码的函数都在"Pascal脚本:支持函数参考"中的InnoSetup帮助文件中列出。
您可以尝试c# to Oxygene转换器,它可以将此转换为Oxygene,这是Delphi Prism中使用的Object Pascal。
问题是这段代码使用了。net类(如StringBuilder)和转换器(Int32.Parse),这些在InnoSetup中是不可用的。
