SpatialEdmFunctions.GeographyMultiPolygonFromBinary Metode

Definisi

Ruang nama:

System.Data.Common.CommandTrees.ExpressionBuilder.Spatial

Rakitan:

System.Data.Entity.dll

DbFunctionExpression Membuat yang memanggil fungsi kanonis 'GeographyMultiPolygonFromBinary' dengan argumen yang ditentukan. multiPolygonWellKnownBinaryValue harus memiliki tipe hasil biner, sementara coordinateSystemId harus memiliki tipe hasil numerik bilangan bulat. Jenis hasil ekspresi adalah Edm.Geography.
