Sachin Singh · Answer

create one static class and a static method anywhere in your project public static class Common { public static string GetCon() { string connectionString = ConfigurationManager.ConnectionStrings[ "Cnn" ].ConnectionString; return connectionString; } } now call this as string cs=Common.GetCon();

Hi, you can't define class property inside it's constructor. Define it as below. namespace MyApplication.Models { public class Common { public static string connectionString = ConfigurationManager.ConnectionStrings[ "Cnn" ].ConnectionString; } }

Salman Beg · Answer

In your solution, create a common class and in that define connection string and wherever you want to access it just use that common class and access that connection string. See this below link for example, https://www.c-sharpcorner.com/UploadFile/7d3362/various-ways-to-specify-connection-string-in-Asp-Net-web-app/ https://stackoverflow.com/questions/13927352/single-declaration-of-connection-string-in-application
