无法将类型字符串隐式转换为byte [] [英] Cannot implicitly convert type string to byte[]

问题描述

我有一个类用加密的哈希加密密码。

I have a class that encrypts a password with a salted hash.

但是如果我想传递一个null类，我得到以下错误：不能将类型字符串隐式转换为byte []

But If I want to pass a null to the class I get the following error: Cannot implicitly convert type string to byte[]

这里是类代码：

public class MyHash
{
    public static string ComputeHash(string plainText, 
                            string hashAlgorithm, byte[] saltBytes)
    {
        Hash Code
    }
}

我收到错误：不能隐式转换类型字符串为byte []

When I use the class I get the error: "Cannot implicitly convert type string to byte[]"

//Encrypt Password
byte[] NoHash = null;
byte[] encds = MyHash.ComputeHash(Password, "SHA256", NoHash);

推荐答案

ComputeHash函数的返回类型是一个字符串。您尝试将函数的结果分配给encds，这是byte []。编译器将这个差异指向你，因为没有从string到byte []的隐式转换。

The return type of your ComputeHash function is a string. You try to assign the result of your function to encds, which is byte[]. The compiler points this discrepancy out to you, because there is no implicit conversion from string to byte[].
