I was hoping to find an easy way to get a parameter list of a stored procedures parameters. If the procedure has 3 paramaters, I want a list like this:

You can do this without ever touching SqlConnection, which I find is a bonus.

This uses the SqlServer.Management.Smo namespace, so you need a reference to Microsoft.SqlServer.ConnectionInfo, Microsoft.SqlServer.Management.Sdk, and Microsoft.SqlServer.Smo in your project.

Then use the following code:

Server srv = new Server("serverNameHere");
srv.ConnectionContext.AutoDisconnectMode = AutoDisconnectMode.NoAutoDisconnect;
srv.ConnectionContext.LoginSecure = false; //if using username/password
srv.ConnectionContext.Login = "username";
srv.ConnectionContext.Password = "password";
srv.ConnectionContext.Connect();

Database db = srv.Databases["databaseNameHere"];

foreach(StoredProcedure sp in db.StoredProcedures)
{
    foreach(var param in sp.Parameters)
    {
        string paramName = param.Name;
        var dataType = param.DataType;
        object defaultValue = param.DefaultValue;
    }
}
