    .Net Encoding convert error


    I have a problem converting a string to a byte array incorrectly.

    StringBuilder str = new StringBuilder;

    str.Appendchar0x80;

    str.Appendchar0x07;

    byte[] result = Encoding.GetEncoding1252.GetBytesstr.ToString;


    A program written in Visual Basic using .Net 2.0 produces the result 80 07

    C# compiler produces output 3F 07

    This is a bug or feature. As a result of this error, a program written in VB does not work correctly with the hardware. Requests vary depending on the localization of Windows.

    :)

    .NET Framework 3.5 installation error: 0x800736B3

    Hi,

    Welcome to Microsoft Community and thank you for your interest in Windows 10.

    I suggest you to follow the below steps to check whether the .NET Framework 3.5 has been installed or not.

    • Press Windows+X and then select programs and features.
    • On the left hand side click on the option “turn windows features on or off”.
    • Check whether the “.NET Framework 3.5” has been checked or not.
    • If not check then I suggest you to check it and then install it.
    Hope this information was helpful and do let us know if you need further assistance. We will be glad to assist.

    Hi,

    Welcome to Microsoft Community.

    I suggest you to un-check and recheck .Net framework 3.5 and .Net framework 4.6 advance series from Windows features.

    Try the following steps:

    • Press Windows + R keys to open Run command.
    • Type Appwiz.cpl and select "turn Windows feature on or off" from the left
    • Uncheck .Net framework 3.5 and .Net framework 4.6 advance series.
    • Restart the computer
    • Repeat step 1 and 2 and check .Net framework 3.5 and .Net framework 4.6 advance series.
    • Restart the computer.
    Regards,

    .Net Encoding convert error

    Unable to download any framework for .net - (error code 0x80070002)

    OK, the Windows 10 Feature installation method should have been straightforward, but since that errored out as well, something else seems to be going on with your Windows, so wait for somebody with more experience to suggest a way out.

    In the mean time, if you haven't already, you could give muchomurka's suggestion a go as well with the elevated prompt and an install media to see if it works. The following link shows the detailed steps involved.
