C# Net 8 handle is not initialized

[liujian]

I am using this a few DLLS to connect libreoffice. I am using the c #,.net core 8.0, but he complains: System. InvalidOperationException: "Handle is not initialized.". Error code: m_xContext = uno. Util. The Bootstrap, Bootstrap ();
But my use of the net framework is fine. May I ask where the operation is not in place, what is the solution? I use machine translation, translation may be wrong

Please insert your complete code as text, not as picture
In your text you mention Libreoffice, in your footer Openoffice. What is true?
32 bit or 64 bit version for LO?

1 Are libreoffice and openoffice the same product?
2 Code I downloaded from libreoffice example, a bit much, the previous package has been uploaded. Upload file I encountered cs file can not upload, upload file number limit
3 I use vs2022 netframework x64 properly, 32 has problems. Both net8 x64 and 32 have problems.

Hi,
this is a very simple example. Try to get this running ...

I have tried this similar code and it works in the NetFramework, but it doesn't work in NetCore
ERROR CODE: XComponentContext XCC = uno.util.Bootstrap.bootstrap();

When working with NetCore, you probably have to link the correct windows dlls. I cannot help you there, sorry. I use csc.exe, see the PowerShell script to get an idea

Code: Select all

param([string]$fileName, [string]$fileNameWithoutExt)
$csc = 'C:\Windows\Microsoft.NET\Framework\v4.0.30319\csc.exe'
$cliPath = 'C:\Program Files\LibreOffice\sdk\cli\'

$fileNameExe = "$($fileNameWithoutExt).exe"

if (Test-Path $fileNameExe -PathType Leaf ) {
    rm $fileNameExe
}

$cmdPars = @('/nologo', '-warnaserror+', '-debug+')

('cli_basetypes', 'cli_uretypes', 'cli_oootypes', 'cli_ure', 'cli_cppuhelper') | foreach{$cmdPars += "-reference:$($cliPath)$($_).dll"}

$cmdPars += $fileName
. $csc $cmdPars

if (Test-Path $fileNameExe -PathType Leaf ) {
    "compiled successfully"
    . ".\$($fileNameExe)"
}
