C# .GetXData(string, object, object);

[Anonymous]

Hello,

How can I read the data that comes out of .GetXData when using C#. The out is a an object???

foreach (AcadEntity ent in doc.PaperSpace)
{
      Object xdataType;
      Object xdatavalue;
      ent.GetXData("test", out xdataType, out xdatavalue);
      //how do i read xdatavalue???
}

Regards

Chris

The output objects (xdataType and xdatavalue) would be either null, or array with at least 1 element (application name). So, you simply cast them as array and loop through them. Something like:

ent.GetXData("test", out xdataType, out xdatavalue);

if (xdataType!=null && xdatavalue!=null)

{

    short[] dTypes=xdataType as short[];

    object[] dValues=xdatavalue as object[];

    for (int i=0; i<dTypes.Length; i++)

    {

        short t=dTypes[i];

        object v=dValues[i];

        switch (t)

        {

            case 1001:

              MessageBox.Show("This is app name: " + v.ToString());

              break;

            case 1000:

              MessageBox.Show("This is text value in XData&colon; " + v.ToString());

              break;

            case ....

        }

    )

}
