建立隨機數字

這段範例程式碼展示了如何在 WinUI 應用程式中建立用於密碼學的隨機數或緩衝區。

public string GenerateRandomData()
{
    // Define the length, in bytes, of the buffer.
    uint length = 32;

    // Generate random data and copy it to a buffer.
    IBuffer buffer = CryptographicBuffer.GenerateRandom(length);

    // Encode the buffer to a hexadecimal string (for display).
    string randomHex = CryptographicBuffer.EncodeToHexString(buffer);

    return randomHex;
}

public uint GenerateRandomNumber()
{
    // Generate a random number.
    uint random = CryptographicBuffer.GenerateRandomNumber();
    return random;
}
