Definisi

Ruang nama:

System.Data.Common.CommandTrees.ExpressionBuilder.Spatial

Rakitan:

System.Data.Entity.dll

DbFunctionExpression Membuat yang memanggil fungsi 'SpatialOverlaps' kanonis dengan argumen yang ditentukan, yang masing-masing harus memiliki jenis hasil Edm.Geometry. Jenis hasil ekspresi adalah Edm.Boolean.

<Extension()>
Public Function SpatialOverlaps (geometryValue1 As DbExpression, geometryValue2 As DbExpression) As DbFunctionExpression

Parameter

geometryValue1

DbExpression

Ekspresi yang menentukan nilai geometri pertama.

geometryValue2

DbExpression

Ekspresi yang menentukan nilai geometri yang harus dibandingkan dengan geometryValue1.

Mengembalikan

DbFunctionExpression

DbFunctionExpression baru yang mengembalikan nilai Boolean yang menunjukkan apakah geometryValue1 tumpang tindih spasial geometryValue2.

Pengecualian

ArgumentNullException

geometryValue1 geometryValue2

ArgumentException

geometryValue1 geometryValue2
