Microsoft.Extensions.Configuration.Binder Specifies options used by the . Gets or sets a value that indicates whether the binder attempts to set all properties or only public properties. if the binder attempts to set all non-read-only properties; if only public properties are set. Gets or sets a value that indicates whether exceptions are thrown when converting a value or when a configuration key is found for which the provided model object doesn't have an appropriate property that matches the key's name. if an is thrown with a description; if no exceptions are thrown. The default is . Static helper class that allows binding strongly typed objects to configuration values. Attempts to bind the configuration instance to a new instance of type T. If this configuration section has a value, that will be used. Otherwise binding by matching property names against configuration keys recursively. The type of the new instance to bind. The configuration instance to bind. The new instance of T if successful, default(T) otherwise. Attempts to bind the configuration instance to a new instance of type T. If this configuration section has a value, that will be used. Otherwise binding by matching property names against configuration keys recursively. The type of the new instance to bind. The configuration instance to bind. Configures the binder options. The new instance of T if successful, default(T) otherwise. Attempts to bind the configuration instance to a new instance of type T. If this configuration section has a value, that will be used. Otherwise binding by matching property names against configuration keys recursively. The configuration instance to bind. The type of the new instance to bind. The new instance if successful, null otherwise. Attempts to bind the configuration instance to a new instance of type T. If this configuration section has a value, that will be used. Otherwise binding by matching property names against configuration keys recursively. The configuration instance to bind. The type of the new instance to bind. Configures the binder options. The new instance if successful, null otherwise. Attempts to bind the given object instance to the configuration section specified by the key by matching property names against configuration keys recursively. The configuration instance to bind. The key of the configuration section to bind. The object to bind. Attempts to bind the given object instance to configuration values by matching property names against configuration keys recursively. The configuration instance to bind. The object to bind. Attempts to bind the given object instance to configuration values by matching property names against configuration keys recursively. The configuration instance to bind. The object to bind. Configures the binder options. Extracts the value with the specified key and converts it to type T. The type to convert the value to. The configuration. The key of the configuration section's value to convert. The converted value. Extracts the value with the specified key and converts it to type T. The type to convert the value to. The configuration. The key of the configuration section's value to convert. The default value to use if no value is found. The converted value. Extracts the value with the specified key and converts it to the specified type. The configuration. The type to convert the value to. The key of the configuration section's value to convert. The converted value. Extracts the value with the specified key and converts it to the specified type. The configuration. The type to convert the value to. The key of the configuration section's value to convert. The default value to use if no value is found. The converted value. Reset the property value to the value from the property getter. This is useful for properties that have a getter or setters that perform some logic changing the object state. The property to reset. The instance to reset the property on. The binder options. This method doesn't do any configuration binding. It just resets the property value to the value from the property getter. This method called only when creating an instance using a primary constructor with parameters names match properties names. Create an instance of the specified type. The type to create an instance of. The configuration to bind to the instance. The binder options. The parameters of the constructor used to create the instance. The created instance. If the type cannot be created. constructorParameters will not be null only when using a constructor with a parameters which get their values from the configuration This happen when using types having properties match the constructor parameter names. `record` types are an example. In such cases we need to carry the parameters list to avoid binding the properties again during BindProperties. Cannot create instance of type '{0}' because it is either abstract or an interface. Cannot create instance of type '{0}' because one or more parameters cannot be bound to. Constructor parameters cannot be declared as in, out, or ref. Invalid parameters are: '{1}' Cannot create instance of type '{0}' because one or more parameters cannot be bound to. Constructor parameters must have corresponding properties. Fields are not supported. Missing properties are: '{1}' Failed to convert configuration value '{0}' at '{1}' to type '{2}'. Failed to create instance of type '{0}'. '{0}' was set and binding has failed. The likely cause is an invalid configuration value. '{0}' was set on the provided {1}, but the following properties were not found on the instance of {2}: {3} Cannot create instance of type '{0}' because it is missing a public instance constructor. Cannot create instance of type '{0}' because it has multiple public parameterized constructors. Cannot create instance of type '{0}' because one or more parameters are unnamed. Cannot create instance of type '{0}' because parameter '{1}' has no matching config. Each parameter in the constructor that does not have a default value must have a corresponding config entry. Cannot create instance of type '{0}' because multidimensional arrays are not supported.
