我创建一个MetroStyle应用程序,我想生成一个MD5 $ C $下我的字符串。到目前为止,我已经用这样的:
I'm creating a MetroStyle app and I want to generate a MD5 code for my string. So far I've used this:
public static string ComputeMD5(string str)
{
try
{
var alg = HashAlgorithmProvider.OpenAlgorithm("MD5");
IBuffer buff = CryptographicBuffer.ConvertStringToBinary(str, BinaryStringEncoding.Utf8);
var hashed = alg.HashData(buff);
var res = CryptographicBuffer.ConvertBinaryToString(BinaryStringEncoding.Utf8, hashed);
return res;
}
catch (Exception ex)
{
return null;
}
}
但它抛出一个异常类型的 System.ArgumentOutOfRangeException
,出现以下错误消息:
but it throws an exception of type System.ArgumentOutOfRangeException
with the following error message:
没有映射为统一code字符存在于多字节的目标code页面。 (从HRESULT异常:0x80070459)
我在做什么错在这里?
确定。我发现如何做到这一点。这里是最后的code:
OK. I've found how to do this. Here's the final code:
public static string ComputeMD5(string str)
{
var alg = HashAlgorithmProvider.OpenAlgorithm(HashAlgorithmNames.Md5);
IBuffer buff = CryptographicBuffer.ConvertStringToBinary(str, BinaryStringEncoding.Utf8);
var hashed = alg.HashData(buff);
var res = CryptographicBuffer.EncodeToHexString(hashed);
return res;
}
