How To Create And Use Enumeration Types In C#

After reading this blog, you will learn the below points,
  • What is Enumeration
  • Advantages
  • Syntax with examples



What is Enumeration?
Enumerations type specifies a group of named numeric constants; it is a user defined type, which means we can create an enumeration type, declare variable to that type and then assign values to those variables.
Main purpose of using enumeration is to represent constant values.
Advantages
  • Makes our code easier to maintain by ensuring our variables are assigned only anticipated values.
  • We can assign identifiable names to the values.
  • Allows us to specify a set of constant values and define a type that will accept values from only that set.
  • When we assign enumeration values, Microsoft intellisense displays a list of possible values that we can use.
Syntax with Example
We can create enumeration type by using enum keyword, assigning a name and then listing the values that our enumeration can take.
Eg

  1. enum Planet {  
  2.     Mercury,  
  3.     Venus,  
  4.     Earth,  
  5.     Mars  
  6. }  

Above code will create a new type, Planet. We can declare variables of this type and assign them values from the enumeration list
When we are referring to a specific member in enumerations, we use enumeration name and dot and then member name as below
Planet innerPlanner = Planet.Earth;
NOTE
We can declare enumeration in a class or a namespace but not in method.

ERROR: Cannot resolve the collation conflict between SQL_Latin1_General_CP1_CI_AS and Latin1_General_CI_AS_KS_WS in the equal to operation

ERROR: Cannot resolve the collation conflict between SQL_Latin1_General_CP1_CI_AS and Latin1_General_CI_AS_KS_WS in the equal to operation
dont get panic if u get the following error while in your joinings, there is a simple way to solve this.
it is because of collation settings on two columns we are doing joinings. it is because of collation settings on two columns we are doing joinings
First step is to figure out what are two colaltion that cause for conflicts. Let us assume that collation has not been set at the column level and instead at db level, then we have to execute two simple statements as below.

Statements: Select DATABASEPROPERTYYEX('DB1',N'Collation') Select DATABASEPROPERTYYEX('DB2',N'Collation')
One more thing, make a note that if you are on sharepoint you will get error as below
Latin_General_CI_AS_KS_WS. if you are on most any other database and use the dafault settings you may get this SQL_Latin_General_CP1_CI_AS.
Now we have to do some…

How To Create The Data Adapter Object Using ADO.NET by #RathrolaPremKumar

By reading this article, you will learn key points in ADO.NET, as given below. What is Data Adapter?Primary Data Adapters for the databases.Data Adapter properties.Methods used by Data Adapter.How to create Data Adapter with an example? Let’s start our demo with a Data Adapter introduction. Actually, we use Data Adapter object to establish the connection to the data source and manage the movement of date to and from the database. What is Data Adapter? A data adapter aobject serves as a bridge between a data set object and Data Source such as a database to retrieve and save the data. Data adapter contains a set of database commands and a database connection, which we use to fill a dataset object and update the Data Source. Primary data adapters for databases? .NET makes two primary data adapters available for use with the databases. Other data adapters can also be integrated with Visual Studio .NET. Primary Data Adapters are mentioned below. OleDbData Adapter, which is suitable for use wi…

Work 9 to 6 for Salary and 6 to 9 for Career

How much time one must spend in office, the subject line of the Post is something I have heard from a client several years back and believe the best of all choices. She was in executive rank and was highly successful in both office & home fronts.................................................................... She said following “Souvik, you get a salary to do 40 hours of work per week. You must come on time at 9 am and work efficiently to plan & finish it by 6 pm. Whatever you are doing during this time, you must try to do it in the best possible way. You should plan so that you do not sign up for more work than what you can deliver. Also manage your priorities & timing to avoid work fluctuations as much as practically possible.”  I nodded head as what she said is something everybody knows. She continued. “However, 9-6 work will only help you “earn” your salary. It will not be good enough to offer a sustained growth, especially in later part of your career. If you really w…
