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)
