.NET Core中的等效System.Data.Linq.Binary

Question

谁能帮助我在.net core中转换此代码：

    private static string GetValueFromModelValue(object formValue)
    {
        //Test to determine if its binary data. If it is, we need to convert it to a base64 string.
        Binary binaryValue = formValue as Binary;
        if (binaryValue != null)
        {
            formValue = binaryValue.ToArray();
        }

        //If the above conversion to an array worked, then the following will cast as a byte array and convert.
        byte[] byteArrayValue = formValue as byte[];
        if (byteArrayValue != null)
        {
            formValue = Convert.ToBase64String(byteArrayValue);
        }

        return formValue.ToString();
    }

System.Data.Linq中的类型在.NET Core和.NET Standard版本（当前为1.0-2.0）中不可用。

由于没有调用者可以传递.NET Core上的Binary对象，因此您可以删除代码或将其放入预处理器定义中（此示例假定针对.NET Core 1.1进行构建）：

#if !NETCOREAPP1_1
Binary binaryValue = …
if (binaryValue != null)
{
    …
}
#endif
