如何在ConfigurationBuilder中使用JSON对象本身而不是文件路径？

Question

我是在k8s群集中存储为configmap的JSON文件。因此，我没有C＃中ConfigurationBuilder类所需的路径。有没有一种方法可以从JSON对象本身而不是FilePath构建配置？

如果您能够从源获取JSON字符串，则可以调用 configurationBuild.add 方法通过将其传递给

以下是示例代码。

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);
    

您也可以致电 addjsonstream 构建器上的方法通过将流传递给它。.

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);
    

我希望这将有助于解决您的问题。
