XML data is often used to transfer data from one application to another. Since XML is language independent, hence it is a good choice to use xml for transferring data between two different platform applications. In C#, it is easy to make xml from database by using LINQ to SQL and LINQ to XML.

Create XML from Database

Suppose we have below table in database. Now I want to make xml of all the products which have stock greater than 0. Here I am using LINQ Pad to query data from the database. It is a great tool to query data from database using LINQ to SQL, LINQ to XML, LINQ to Entity Framework.

 CREATE TABLE Product (
 ProductID int IDENTITY(1,1) NOT NULL,
 ProductName varchar(50) NOT NULL,
 Price float NOT NULL,
 Stock int NOT NULL
)
GO
INSERT INTO Product (ProductName,Price,Stock)VALUES('P001',12.12,100)
INSERT INTO Product (ProductName,Price,Stock)VALUES('P002',102.12,200)
INSERT INTO Product (ProductName,Price,Stock)VALUES('P003',104.12,500)
INSERT INTO Product (ProductName,Price,Stock)VALUES('P004',108.12,100)
INSERT INTO Product (ProductName,Price,Stock)VALUES('P005',72.12,10)
INSERT INTO Product (ProductName,Price,Stock)VALUES('P006',72.12,0)
GO
SELECT * FROM Product 

Now, query the data from above table using LINQ. We can also save the output to xml file.

 //Export above xml to xmlfile
XElement.Save(Server.MapPath(@"~/export.xml"));
