How to: Create a list in sharepoint programmatically

Before creating a list it’s better to check your newly created list already exists in the specified web or not and also if you are creating new list by using custom list template, we have to check if list template exists or not also.

Here is the code to create a list in SharePoint programmatically

//To create a list
#region List Template
String ListTemplateName=”CustomListTemplateName”;
String ListName=”CustomListName”;
SPListTemplateCollection listTempColl = currentSite.GetCustomListTemplates(currentSite.RootWeb);
//checking if the list template exists or not before creating a list reason we are creating a custom list using custom template)
if (IsListTemplateExists(ListTemplateName, listTempColl) == true)
 {
   //Creating the custom list using custom list template.
     SPListTemplate listQuickLinksTemp = listTempColl[ListTemplateName];
     CreateList(currentWeb, ListName, "Description of the list", listQuickLinksTemp);
  }
