C#以编程方式创建.SNK文件

如何以编程方式创建

.snk

文件并将其保存到桌面？ 除了如何从代码中创建

.snk

文件而不打开visual studio命令提示符之外，我什么都懂。但是可以单击表单上的按钮并生成桌面密钥。

以下是一些可以创建有效.snk文件的C#实用程序代码：

示例用法：

...
// write a .snk file
StrongNameUtilities.GenerateKeyFile("test.snk"); // default key size is 1024 bits

// reread an check it worked
var pk = StrongNameUtilities.GetPublicKey("test.snk");
...

公用事业代码：

public sealed class StrongNameUtilities
{
    public static byte[] GetPublicKeyToken(byte[] publicKey)
    {
        if (publicKey == null)
            throw new ArgumentNullException(nameof(publicKey));

        var blob = IntPtr.Zero;
        try
        {
            if (!StrongNameTokenFromPublicKey(publicKey, publicKey.Length, out blob, out var size))
                throw new Win32Exception(StrongNameErrorInfo());

            var bytes = new byte[size];
            Marshal.Copy(blob, bytes, 0, size);
            return bytes;
        }
        finally
        {
            if (blob != IntPtr.Zero)
            {
                StrongNameFreeBuffer(blob);
            }
        }

        if (snkFile == null)

看一看：它可能会给你一些与指针相关的信息，可能是dup@enkryptor，或者我已经看过了，但代码不起作用。@Swoomi介意在问题中添加细节吗？
