SqlCommand.CommandType Property
Gets or sets a value indicating how the CommandText property is to be interpreted.
Namespace: System.Data.SqlClient
Assembly: System.Data (in System.Data.dll)
| Exception | Condition |

| ArgumentException | The value was not a valid CommandType. |
When you set the CommandType property to StoredProcedure, you should set the CommandText property to the name of the stored procedure. The command executes this stored procedure when you call one of the Execute methods.
The Microsoft .NET Framework Data Provider for SQL Server does not support the question mark (?) placeholder for passing parameters to a SQL Statement or a stored procedure called with a CommandType of Text. In this case, named parameters must be used. For example:
SELECT * FROM Customers WHERE CustomerID = @CustomerID
For more information, see Configuring Parameters and Parameter Data Types (ADO.NET).
The following example creates a SqlCommand and sets some of its properties.
Windows 8, Windows Server 2012, Windows 7, Windows Vista SP2, Windows Server 2008 (Server Core Role not supported), Windows Server 2008 R2 (Server Core Role supported with SP1 or later; Itanium not supported)
The .NET Framework does not support all versions of every platform. For a list of the supported versions, see .NET Framework System Requirements.
