A field initializer cannot reference the non-static field, method, or property 'MyController._config'

Question

In .Net Core MVC, I'm trying to get value from app settings to MyController by implementing the below code:

public MyController(IConfiguration config)
{
    _config = config;
}
private string ApiKey = _config.GetValue<string>("ApiKey");

But I get the below error:

A field initializer cannot reference the non-static field, method, or property 'NafathController._config'

Answer 1

Solving: A field initializer cannot reference the non-static field, method, or property

To solve this error you must change your field to a property, by adding Greater-than sign > just like that:

private string ApiKey => _config.GetValue<string>("ApiKey");

• When using = it's create new field.
• When using => you are creating a get-only property.
