POStatic Indexers?
text
Body
copied!<p>Why are static indexers disallowed in C#? I see no reason why they should not be allowed and furthermore they could be very useful.</p> <p>For example:</p> <pre><code>static class ConfigurationManager { public object this[string name]{ get{ return ConfigurationManager.getProperty(name); } set { ConfigurationManager.editProperty(name, value); } } /// <summary> /// This will write the value to the property. Will overwrite if the property is already there /// </summary> /// <param name="name">Name of the property</param> /// <param name="value">Value to be wrote (calls ToString)</param> public static void editProperty(string name, object value) { DataSet ds = new DataSet(); FileStream configFile = new FileStream("./config.xml", FileMode.OpenOrCreate); ds.ReadXml(configFile); if (ds.Tables["config"] == null) { ds.Tables.Add("config"); } DataTable config = ds.Tables["config"]; if (config.Rows[0] == null) { config.Rows.Add(config.NewRow()); } if (config.Columns[name] == null) { config.Columns.Add(name); } config.Rows[0][name] = value.ToString(); ds.WriteXml(configFile); configFile.Close(); } public static void addProperty(string name, object value) { ConfigurationManager.editProperty(name, value); } public static object getProperty(string name) { DataSet ds = new DataSet(); FileStream configFile = new FileStream("./config.xml", FileMode.OpenOrCreate); ds.ReadXml(configFile); configFile.Close(); if (ds.Tables["config"] == null) { return null; } DataTable config = ds.Tables["config"]; if (config.Rows[0] == null) { return null; } if (config.Columns[name] == null) { return null; } return config.Rows[0][name]; } } </code></pre> <p>The above code would benefit greatly from a static indexer. However it won't compile because static indexers are not allowed. Why is this so?</p>
