创建随机数

此示例代码演示如何创建随机数或缓冲区，以便在 通用 Windows 平台 （UWP） 应用中用于加密。

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;
}
