ArcGIS.Core.Data Namespace / Table Class / GetDefinition Method
Example

In This Topic
    GetDefinition Method (Table)
    In This Topic
    Gets the TableDefinition of this dataset. This method must be called on the MCT. Use QueuedTask.Run.
    Syntax
    public new TableDefinition GetDefinition()
    Public Shadows Function GetDefinition() As TableDefinition

    Return Value

    The TableDefinition of this dataset.
    Exceptions
    ExceptionDescription
    This dataset does not have a valid definition.
    A geodatabase-related exception has occurred.
    Remarks
    This routine will throw an exception if called on a joined table, since there is no underlying datastore for these temporary datasets. IsJoinedTable can be used to determine if this table represents a join.
    Example
    Getting a Table Definition from a Layer
    // GetDefinitionFromLayer - This code works even if the layer has a join to another table
    private TableDefinition GetDefinitionFromLayer(FeatureLayer featureLayer)
    {
      // Get feature class from the layer
      FeatureClass featureClass = featureLayer.GetFeatureClass();
    
      // Determine if feature class is a join
      if (featureClass.IsJoinedTable())
      {
        // Get join from feature class
        Join join = featureClass.GetJoin();
    
        // Get origin table from join
        Table originTable = join.GetOriginTable();
    
        // Return feature class definition from the join's origin table
        return originTable.GetDefinition();
      }
      else
      {
        return featureClass.GetDefinition();
      }
    }
