### Files API
The `AnthropicApiClient` provides support for the Anthropic Files API, which allows you to upload and manage files for use with the Anthropic API.
#### Create a File
You can create a file using the Files API in several ways:
##### From a Byte Array
```csharp
using AnthropicClient;
using AnthropicClient.Models;
using System.Text;
// Create a file from a byte array
var content = "This is a sample text file for the Anthropic Files API.";
var fileBytes = Encoding.UTF8.GetBytes(content);
var request = new CreateFileRequest(fileBytes, "sample.txt", "text/plain");
var response = await client.CreateFileAsync(request);
if (response.IsSuccess)
{
Console.WriteLine("File created successfully from byte array!");
Console.WriteLine("File ID: {0}", response.Value.Id);
Console.WriteLine("File Name: {0}", response.Value.FileName);
Console.WriteLine("File Type: {0}", response.Value.FileType);
Console.WriteLine("File Size: {0} bytes", response.Value.SizeBytes);
}
else
{
Console.WriteLine("Failed to create file");
Console.WriteLine("Error Type: {0}", response.Error.Error.Type);
Console.WriteLine("Error Message: {0}", response.Error.Error.Message);
}
```
##### From a Stream
```csharp
using AnthropicClient;
using AnthropicClient.Models;
using System.Text;
// Create a file from a stream
using var stream = new MemoryStream(Encoding.UTF8.GetBytes("Stream content"));
var request = new CreateFileRequest(stream, "stream-file.txt", "text/plain");
var response = await client.CreateFileAsync(request);
if (response.IsSuccess)
{
Console.WriteLine("File created successfully from stream!");
Console.WriteLine("File ID: {0}", response.Value.Id);
}
else
{
Console.WriteLine("Failed to create file");
Console.WriteLine("Error Type: {0}", response.Error.Error.Type);
Console.WriteLine("Error Message: {0}", response.Error.Error.Message);
}
```
> [!NOTE]
> The Files API has certain limitations on file size, supported file types, and usage quotas. Please refer to the [Anthropic API Documentation](https://docs.anthropic.com/en/docs/build-with-claude/files) for the most up-to-date information on these limitations.
### Create a message
The `AnthropicApiClient` exposes a method named `CreateMessageAsync` that can be used to create a message. The method requires a `MessageRequest` or a `StreamMessageRequest` instance as a parameter. The `MessageRequest` class is used to create a message whose response is not streamed and the `StreamMessageRequest` class is used to create a message whose response is streamed. The `MessageRequest` instance's properties can be set to configure how the message is created.
