SpatialEdmFunctions.GeometryLineFromBinary(DbExpression, DbExpression) Metode

Definisi

Ruang nama:

System.Data.Common.CommandTrees.ExpressionBuilder.Spatial

Rakitan:

System.Data.Entity.dll

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

Public Function GeometryLineFromBinary (lineWellKnownBinaryValue As DbExpression, coordinateSystemId As DbExpression) As DbFunctionExpression

Parameter

lineWellKnownBinaryValue

DbExpression

coordinateSystemId

DbExpression

Ekspresi yang menyediakan id sistem koordinat (SRID) dari sistem koordinat nilai garis geometri.

Mengembalikan

DbFunctionExpression

DbFunctionExpression baru yang mengembalikan nilai baris geometri baru berdasarkan nilai yang ditentukan.

Pengecualian
