SpatialEdmFunctions.GeographyCollectionFromBinary 方法

定義

命名空間:

System.Data.Common.CommandTrees.ExpressionBuilder.Spatial

組件:

System.Data.Entity.dll

建立一個使用指定引數叫用標準 'GeographyCollectionFromBinary' 函式的 DbFunctionExpression。 geographyCollectionWellKnownBinaryValue 必須具有二進位結果型別，而 coordinateSystemId 必須具有整數數值結果型別。 運算式的結果型別為 Edm.Geography。

public:
 static System::Data::Common::CommandTrees::DbFunctionExpression ^ GeographyCollectionFromBinary(System::Data::Common::CommandTrees::DbExpression ^ geographyCollectionWellKnownBinaryValue, System::Data::Common::CommandTrees::DbExpression ^ coordinateSystemId);

public static System.Data.Common.CommandTrees.DbFunctionExpression GeographyCollectionFromBinary (System.Data.Common.CommandTrees.DbExpression geographyCollectionWellKnownBinaryValue, System.Data.Common.CommandTrees.DbExpression coordinateSystemId);

static member GeographyCollectionFromBinary : System.Data.Common.CommandTrees.DbExpression * System.Data.Common.CommandTrees.DbExpression -> System.Data.Common.CommandTrees.DbFunctionExpression

Public Function GeographyCollectionFromBinary (geographyCollectionWellKnownBinaryValue As DbExpression, coordinateSystemId As DbExpression) As DbFunctionExpression

參數

geographyCollectionWellKnownBinaryValue

DbExpression

提供地理集合值之已知二進位表示的運算式。

coordinateSystemId

DbExpression

運算式，提供地理集合值之座標系統的座標系統 ID (SRID)。

傳回

DbFunctionExpression

根據指定值傳回新地理集合值的新 DbFunctionExpression。

例外狀況

ArgumentNullException

geographyCollectionWellKnownBinaryValue coordinateSystemId

ArgumentException

geographyCollectionWellKnownBinaryValue coordinateSystemId
