C#如何创建字段？（急急急）

IFieldEdit pField=new FieldClass();

           
  pField.Name_2 ="hjh";
  pField.Type_2  = esriFieldType.esriFieldTypeString;
  pField.Length_2  = 50;
  pTable.AddField(pField);

可在c#中pFieldEdit pFieldsEdit等提示属性是只读的，不能赋值

俺给你个代码：

Public Function CreateShapefile(sPath As String, sName As String, sSpatial As ISpatialReference) As IFeatureClass  ' 名称不要加.shp后缀  
  Dim pFWS As IFeatureWorkspace
  Dim pWorkspaceFactory As IWorkspaceFactory
  Set pWorkspaceFactory = New ShapefileWorkspaceFactory
  Set pFWS = pWorkspaceFactory.OpenFromFile(sPath, 0)
 
  Dim pFields As IFields
  Dim pFieldsEdit As IFieldsEdit
  Set pFields = New Fields
  Set pFieldsEdit = pFields
 
  Dim pField As iField
  Dim pFieldEdit As IFieldEdit
 
  Set pField = New Field
  Set pFieldEdit = pField
  pFieldEdit.name = "Shape"
  pFieldEdit.Type = esriFieldTypeGeometry
 
  Dim pGeomDef As IGeometryDef
  Dim pGeomDefEdit As IGeometryDefEdit
  Set pGeomDef = New GeometryDef
  Set pGeomDefEdit = pGeomDef

  With pGeomDefEdit

     .GeometryType = esriGeometryPolygon
     Set .SpatialReference = sSpatial ' New UnknownCoordinateSystem

  End With

  Set pFieldEdit.GeometryDef = pGeomDef
  pFieldsEdit.AddField pField
 
  Set pField = New Field
  Set pFieldEdit = pField

  With pFieldEdit

     .length = 30
     .name = "MiscText"
     .Type = esriFieldTypeString

  End With

  pFieldsEdit.AddField pField
 
  Dim pFeatClass As IFeatureClass
  Set pFeatClass = pFWS.CreateFeatureClass(sName, pFields, Nothing, _
     Nothing, esriFTSimple, "Shape", "")
                                           
  Set CreateShapefile = pFeatClass

End Function
