This example sets a linetype current through the Database object with the Celtype property.

C# Example

using Autodesk.AutoCAD.Runtime;
using Autodesk.AutoCAD.ApplicationServices;
using Autodesk.AutoCAD.DatabaseServices;
 
[CommandMethod("SetLinetypeCurrent")]
public static void SetLinetypeCurrent()
{
    // Get the current document and database
    Document acDoc = Application.DocumentManager.MdiActiveDocument;
    Database acCurDb = acDoc.Database;

    // Start a transaction
    using (Transaction acTrans = acCurDb.TransactionManager.StartTransaction())
    {
        // Open the Linetype table for read
        LinetypeTable acLineTypTbl;
        acLineTypTbl = acTrans.GetObject(acCurDb.LinetypeTableId,
                                         OpenMode.ForRead) as LinetypeTable;

        string sLineTypName = "Center";

        if (acLineTypTbl.Has(sLineTypName) == true)
        {
            // Set the linetype Center current
            acCurDb.Celtype = acLineTypTbl[sLineTypName];

            // Save the changes
            acTrans.Commit();
        }

        // Dispose of the transaction
    }
}
