SpatialEdmFunctions.SpatialIntersection(DbExpression, DbExpression) Metode

Definisi

Ruang nama:

System.Data.Common.CommandTrees.ExpressionBuilder.Spatial

Rakitan:

System.Data.Entity.dll

DbFunctionExpression Membuat yang memanggil fungsi 'SpatialIntersection' kanonis dengan argumen yang ditentukan, yang masing-masing harus memiliki jenis hasil Edm.Geography atau Edm.Geometry. Jenis spatialValue1 hasil harus cocok dengan jenis hasil .spatialValue2 Jenis hasil ekspresi sama dengan jenis spatialValue1 dan spatialValue2.

<Extension()>
Public Function SpatialIntersection (spatialValue1 As DbExpression, spatialValue2 As DbExpression) As DbFunctionExpression

Parameter

spatialValue1

DbExpression

Ekspresi yang menentukan nilai spasial pertama.

spatialValue2

DbExpression

Ekspresi yang menentukan nilai spasial yang irisannya spatialValue1 harus dihitung.

Mengembalikan

DbFunctionExpression

DbFunctionExpression baru yang mengembalikan nilai spasial yang mewakili persimpangan spatialValue1 dan spatialValue2.

Pengecualian

ArgumentNullException

spatialValue1 spatialValue2

ArgumentException

spatialValue1 spatialValue2
