Class ConfigurationManager

Namespace

Dynamicweb.Configuration

Assembly

Dynamicweb.Core.dll

Class for managing configuration values. Uses a provider that defines where configuration values are stored. The default configuration manager is accessed through SystemConfiguration which uses the XmlConfigurationProvider to return values from settings stored in /Files/*.config files.

        void Configure()
        {
            // Setting a configuration value
            SystemConfiguration.Instance.SetValue("/Globalsettings/Modules/MyModule/Feature", true);

            // Getting a configuration setting as a string value
            string dbserver = SystemConfiguration.Instance.GetValue("/Globalsettings/System/Database/Server");

            // Getting a configuration setting as an integer value
            int maxAttempts = SystemConfiguration.Instance.GetInt32("/Globalsettings/Modules/MyModule/MaxAttempts");

            // Getting a configuration setting as a boolean value
            bool useFeature = SystemConfiguration.Instance.GetBoolean("/Globalsettings/Modules/MyModule/UseFeature");

            // Getting a configuration setting using TryGet
            string apiKey;
            if (SystemConfiguration.Instance.TryGet("/Globalsettings/Modules/MyModule/ApiKey", out apiKey))
            {
                if (!string.IsNullOrEmpty(apiKey))
                {

                }
            }
        }
    }
}

Remarks

Implement IConfigurationProvider to add configuration providers that can store and retrieve settings from other sources.

Constructors

ConfigurationManager()

Creates a new instance of ConfigurationManager.

public ConfigurationManager()

Methods

AddProvider(IConfigurationProvider)

Adds an instance of IConfigurationProvider. This enables multiple providers to contribute the the same ConfigurationManager.

public void AddProvider(IConfigurationProvider provider)

Parameters

provider IConfigurationProvider

The provider to add.

AddProviderPriority(IConfigurationProvider)

Adds an instance of IConfigurationProvider as the first provider in the provider list giving it priority over the system configuration provider. This enables multiple providers to contribute the the same ConfigurationManager.

public void AddProviderPriority(IConfigurationProvider provider)

Parameters

provider IConfigurationProvider

The provider to add.

Contains(string)

Determines whether the configuration contains the specified key.

public virtual bool Contains(string key)

Parameters

key string

The key that represents the value, e.g. "/Globalsettings/System/Database/Trusted"

Returns

bool

true if the configuration contains an entry with the specified key; otherwise,

false

.

GetBoolean(string)

Gets the bool value for the specified key.

public virtual bool GetBoolean(string key)

Parameters

key string

The key that represents the value to get, e.g. "/Globalsettings/System/Database/Trusted"

Returns

bool

The value converted to bool if the key exists and is a valid boolean string in configuration file (True, 1, On), otherwise

false

.

GetDouble(string)

Gets the double value for the specified key.

public virtual double GetDouble(string key)

Parameters

key string

The key that represents the value, e.g. "/Globalsettings/System/Database/Trusted"

Returns

double

The value converted to int if the key exists, otherwise

0

.

GetInt32(string)

Gets the int value for the specified key.

public virtual int GetInt32(string key)

Parameters

key string

The key that represents the value, e.g. "/Globalsettings/System/Database/Trusted"

Returns

int

The value converted to int if the key exists, otherwise

0

.

GetKeys()

Gets all keys that can be used to get or set data.

public ICollection<string> GetKeys()

Returns

ICollection<string>

keys

GetValue(string)

Gets the string value for the specified key.

public virtual string GetValue(string key)

Parameters

key string

The key that represents the value to get, e.g. "/Globalsettings/System/Database/Trusted"

Returns

string

The string value if it exists, otherwise Empty.

SetValue(Dictionary<string, string>)

Sets a collection configuration entries.

public virtual void SetValue(Dictionary<string, string> keyValues)

Parameters

keyValues Dictionary<string, string>

The key/value pairs to set.

SetValue<T>(string, T)

Sets value of the entry with the specified key.

public virtual void SetValue<T>(string key, T value) where T : IConvertible

Parameters

key string

The key that represents the value, e.g. "/Globalsettings/System/Database/Trusted"

value T

The value of the element to add to the configuration file. Should be simple value types like string, bool, int or double.

Type Parameters

T

The type of the value.

TryGet<T>(string, out T?)

Attempts to get the value associated with the specified key.

public virtual bool TryGet<T>(string key, out T? value) where T : IConvertible

Parameters

key string

The key that represents the value, e.g. "/Globalsettings/System/Database/Trusted"

value T

When this method returns, contains the value associated with the specified key, or the default value of the type if the key was not found.

Returns

bool

true if the specified key was found; otherwise, false.

Type Parameters

T

The type of the value.
