How do I run a .sql file with multiple 'GO' statements into Visual Studio c# windows form?

Question

This is my .sql file, it's saved as "Split.sql" and is located in C:\

INSERT Employee (Name)
    values ('Roland Eric Real')
SELECT *  FROM Employee
GO

select 
    Name, 
    -- instead of spaces you can use any delimiter that you have like a comma
    -- We replace the delimiter with dot, which is used by the function PARSENAME
    PARSENAME( REPLACE(Name, ' ','.') ,3) as LastName, 
    PARSENAME( REPLACE(Name, ' ','.') ,2) as FirstName, 
    PARSENAME( REPLACE(Name, ' ','.') ,1) as MiddleName
from Employee
GO

-- If you need to alter the table then
-- Alter the table and add new columns
ALTER TABLE Employee
ADD LastName varchar(50),
    FirstName varchar(50),
    MiddleName varchar(50)
GO

-- Moving the data from FullName to the new columns
UPDATE Employee SET 
    LastName   = PARSENAME( REPLACE(Name, ' ','.') ,3), 
    FirstName  = PARSENAME( REPLACE(Name, ' ','.') ,2), 
    MiddleName = PARSENAME( REPLACE(Name, ' ','.') ,1)
GO

SELECT *  FROM Employee
GO

-- Now we can drop the old column
ALTER TABLE Employee
 DROP COLUMN Name
GO

-- Reclaim space by rebuilt the table
ALTER TABLE Employee REBUILD 
GO

SELECT *  FROM Employee
GO

I am using windows form in visual studio c#. Basically, when I press a button in windows form, I want it to run that code in sql. Any help would be appreciated, thank you. ^_^
