Why Dictionary is serializable ?

Question

Does anyone know the reason why Dictionary is serializable ?

Niradhip Chakraborty · Answer

a .NET class called KeyedCollection. KeyedCollection derives from the iList interface instead of iDictionary, and is therefore serializable. So if you need a keyed list and your objects include unique values, you can use KeyedCollection and get the benefits of serialization as well.

Hi When you are look .net class lib for the dictonarty, it inherited from some basic object. take look the snap shot Normal 0 false false false EN-US X-NONE X-NONE MicrosoftInternetExplorer4 /* Style Definitions */ table.MsoNormalTable {mso-style-name:"Table Normal"; mso-tstyle-rowband-size:0; mso-tstyle-colband-size:0; mso-style-noshow:yes; mso-style-priority:99; mso-style-qformat:yes; mso-style-parent:""; mso-padding-alt:0in 5.4pt 0in 5.4pt; mso-para-margin-top:0in; mso-para-margin-right:0in; mso-para-margin-bottom:10.0pt; mso-para-margin-left:0in; line-height:115%; mso-pagination:widow-orphan; font-size:11.0pt; font-family:"Calibri","sans-serif"; mso-ascii-font-family:Calibri; mso-ascii-theme-font:minor-latin; mso-fareast-font-family:"Times New Roman"; mso-fareast-theme-font:minor-fareast; mso-hansi-font-family:Calibri; mso-hansi-theme-font:minor-latin;} using System; using System .
