<p>I am gettin the json file stored as ConfigMap in K8s cluster. So I do not have the path as required in ConfigurationBuilder class in C#. Is there a way to build configuration from JSON object itself rather than the filepath ?</p>

<p>If you are able to get the JSON string from the source,  you can call <a href="https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.configuration.configurationbuilder.add?view=dotnet-plat-ext-6.0" rel="nofollow noreferrer">ConfigurationBuild.Add</a> method by passing it an object of <a href="https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.configuration.json.jsonstreamconfigurationsource?view=dotnet-plat-ext-6.0" rel="nofollow noreferrer">JsonStreamConfigurationSource</a> class.</p>
<p>Following is the sample code.</p>
<pre><code>ConfigurationBuilder builder = new ConfigurationBuilder();

// GetConfigJson method should get the JSON string from the source.
// I am leaving the implementation of that method up to you.
string jsonData = GetConfigJson();
    
// Load the JSON into MemoryStream
var stream = new MemoryStream(Encoding.UTF8.GetBytes(jsonData));
    
// Create an object of JsonStreamConfigurationSource class.
var configSource = new JsonStreamConfigurationSource();

// Assign stream to it.
configSource.Stream = stream;

// Call Add method of builder by passing the configSource object.
builder.Add(configSource);
    
</code></pre>
<p>You can also call <a href="https://learn.microsoft.com/en-us/dotnet/api/microsoft.extensions.configuration.jsonconfigurationextensions.addjsonstream?view=dotnet-plat-ext-6.0" rel="nofollow noreferrer">AddJsonStream</a> method on builder by passing the stream to it..</p>
<pre><code>ConfigurationBuilder builder = new ConfigurationBuilder();

// GetConfigJson method should get the JSON string from the source.
// I am leaving the implementation of that method up to you.
string jsonData = GetConfigJson();
    
// Load the JSON into MemoryStream
var stream = new MemoryStream(Encoding.UTF8.GetBytes(jsonData));

// Call AddJsonStream method of builder by passing the stream object.
builder.AddJsonStream(stream);
    
</code></pre>
<p>I hope this will help resolve you issue.</p>
