Remarks

IFieldEdit2 provides access to the raster definition of a raster field in a geodatabase. You can set the spatial reference, alias to the raster field and for PGDB, and you can specify whether the field is managed by the geodatabase.  RasterDef is required for a raster field.

[C#]

The following code shows how to add a raster field to a feature class:

// Create a RasterDef.
IRasterDef rasterDef = new RasterDefClass();
rasterDef.Description = "Raster Field";
rasterDef.IsManaged = true;
rasterDef.SpatialReference = spatialRef;

// Create a raster field.
IField field = new FieldClass();
IFieldEdit2 fieldEdit2 = (IFieldEdit2)field;
fieldEdit2.Name_2 = "Raster";
fieldEdit2.Type_2 = esriFieldType.esriFieldTypeRaster;
fieldEdit2.RasterDef = rasterDef;

// Add the field to the feature class.
featureClass.AddField(field);

[Visual Basic .NET]

The following code shows how to add a raster field to a feature class:

' Create a RasterDef.
Dim rasterDef As IRasterDef = New RasterDefClass()
RasterDef.Description = "Raster Field"
RasterDef.IsManaged = True
RasterDef.SpatialReference = spatialRef

' Create a raster field.
Dim field As IField = New FieldClass()
Dim fieldEdit2 As IFieldEdit2 = CType(field, IFieldEdit2)
fieldEdit2.Name_2 = "Raster"
fieldEdit2.Type_2 = esriFieldType.esriFieldTypeRaster
fieldEdit2.RasterDef = RasterDef

' Add the field to the feature class.
featureClass.AddField(Field)
