使用 TryAsync 和 Bind 方法使用 Language-ext 处理 C# 错误

问：

我尝试使用 和 来自 Language-ext，但没有成功。这是我最接近实现它的地方。TryAsyncBind

public virtual async Task Execute(SignDocumentCommand signDocumentCommand)
{
    (await converterRepository.FindByDocumentId(signDocumentCommand.DocumentId)).Match(
        Right: converterFindSuccessfully => 
            TryToBuildSigner(
                signDocumentCommand, 
                converterFindSuccessfully.Converter.CountryId, 
                converterFindSuccessfully.Converter.SupplierId), 
        Left: converterFindFailed =>
        {
            // TODO: ...
        });
}

private void TryToBuildSigner(
    SignDocumentCommand signDocumentCommand, 
    CountryId countryId,
    SupplierId supplierId)
{
    signerBuilder.Build(countryId, supplierId).Match(
        Right: async signerBuildSuccessful => 
            await TryToSignDocument(signDocumentCommand, signerBuildSuccessful.Signer),
        Left: signerBuildFailed => {
              // TODO: ...
        });
}

private async Task TryToSignDocument(SignDocumentCommand signDocumentCommand, Domain.Signer signer)
{
    var documentToSign = await documentToSignRepository.FindByDocumentId(signDocumentCommand.DocumentId);
    
    (await signer.Sign(documentToSign)).Match(
        Right: async signDocumentSuccessful =>
        {
            var signedDocument = new SignedDocument(
                DocumentId: signDocumentCommand.DocumentId,
                CorrelationId: signDocumentCommand.CorrelationId,
                Content: signDocumentSuccessful.DocumentContent);
            
            await TryToSaveDocumentSigned(signedDocument);
        },
        Left: signDocumentFailed =>
        {
            // TODO: ...
        });
}

private async Task TryToSaveDocumentSigned(SignedDocument signedDocument)
{
    (await signedDocumentRepository.Save(signedDocument))
        .Match(
            Right: async signedDocumentSaveSuccessful => 
                await TryToPublishDocumentSigned(signedDocument),
            Left: signedDocumentSaveFailed =>
            {
                    // TODO: Hacer acción cuándo el documento no se ha podido guardar.
            });
}

private async Task TryToPublishDocumentSigned(SignedDocument signedDocument)
{
    (await publisher.Publish(signedDocument)).Match(
        Right: successfulPublish =>
        {
            // TODO: ...
        },
        Left: failedPublish =>
        {
            // TODO: ...
        });
}

从这里开始，我该如何改进我的代码以使用？我正在尝试做本文的最后一个示例。Bind

类似的东西

  .Bind(SignedDocument)
            .Bind(SearchSigner)
            .Bind(Sign)
            .Bind(Save)
            .Bind(Publish)
            .Match(...);

我也无法使用，也注意到对于每种方法，失败的过程都是不同的，对于所有方法来说都不一样。那么，我该如何实现这一目标呢？是否可能或有任何其他方法？谢谢！TryTryAsync
