How to add files to an existing Vector Store?

[lovedeepatsgit]

I have used AzureAiAgents following (

semantic-kernel/dotnet/samples/GettingStartedWithAgents/AzureAIAgent/Step05_AzureAIAgent_FileSearch.cs

Line 16 in e936f93

public async Task UseFileSearchToolWithAgentAsync()

), I have used AzureAiFoundary Also, there we can add files to an existing Vector Store, but how we can do this through .Net SDK, I know there are methods like ModifyvectorStore, and ModifyVectorStoreAsync (https://learn.microsoft.com/en-us/dotnet/api/azure.ai.projects.agentsclient.modifyvectorstore?view=azure-dotnet-preview#azure-ai-projects-agentsclient-modifyvectorstore(system-string-azure-core-requestcontent-azure-requestcontext), and also CreateVector (https://learn.microsoft.com/en-us/dotnet/api/azure.ai.projects.agentsclient.createvectorstore?view=azure-dotnet-preview#azure-ai-projects-agentsclient-createvectorstore(system-collections-generic-ienumerable((system-string))-system-string-azure-ai-projects-vectorstoreconfiguration-azure-ai-projects-vectorstoreexpirationpolicy-azure-ai-projects-vectorstorechunkingstrategyrequest-system-collections-generic-ireadonlydictionary((system-string-system-string))-system-threading-cancellationtoken)), but files can only be provided during the creation of this Vector Store, but if I have already created a vector store, and i have vector store id, how I can upload files to that specific vector Store.

Hi @lovedeepatsgit,

Adding a file to an existing vector-store requires roughly the same steps as creating one:

1. Upload the file
2. Add it to the vector store

// #1
PersistentAgentFileInfo fileInfo = await agentsClient.Files.UploadFileAsync(stream, PersistentAgentFilePurpose.Agents, "<filename>");
// #2
await agentsClient.VectorStores.CreateVectorStoreFileAsync("<storeid>", fileInfo.Id);
