How can the code changes associated with each commit ID be extracted using the AzureDevOps API?

edit

To extract the code changes associated with each commit ID using the AzureDevOps API, you can use the following steps:

1. First, you need to authenticate with AzureDevOps using a Personal Access Token (PAT).
2. Then, you can use the CoreHttpClient to get the code changes associated with a particular commit ID.
3. Use the GitHttpClient to get the repository details.
4. Use the GitHttpClient again to get the changes associated with each commit ID.
5. Finally, you can extract the code changes from each commit ID by parsing the changeType property.

Here is an example code snippet to extract the code changes associated with each commit ID using the AzureDevOps API:

// Authenticate with AzureDevOps using a Personal Access Token (PAT).
string personalAccessToken = "YOUR_PAT";
VssConnection connection = new VssConnection(new Uri("https://dev.azure.com/YOUR_ORGANIZATION"), new VssBasicCredential(string.Empty, personalAccessToken));

// Get the code changes associated with a particular commit ID.
string commitId = "COMMIT_ID";
var gitClient = connection.GetClient<GitHttpClient>();
var changes = gitClient.GetChangesAsync("YOUR_PROJECT_NAME", "YOUR_REPO_NAME", new GitQueryCommitsCriteria() {Ids = new List<string>() { commitId } }).Result;

// Get the repository details.
var repo = gitClient.GetRepositoryAsync("YOUR_PROJECT_NAME", "YOUR_REPO_NAME").Result;

// Get the changes associated with each commit ID.
var coreClient = connection.GetClient<CoreHttpClient>();
var changeDetails = new List<string>();
foreach (var change in changes.First().Changes)
{
    if (change.Item.Path.StartsWith($"{repo.Name}/"))
    {
        var changeDetail = $"Path: {change.Item.Path}\nChange Type: {change.ChangeType}\n";
        changeDetails.Add(changeDetail);
    }
}

// Parse the `changeType` property to extract the code changes.
foreach (var changeDetail in changeDetails)
{
    Console.WriteLine(changeDetail);
    // Here, you can extract the code changes by parsing the `changeType` property.
}
