SpatialEdmFunctions.GeometryMultiPolygonFromBinary 方法

定义

创建使用指定参数调用规范“GeometryMultiPolygonFromBinary”函数的 DbFunctionExpressionmultiPolygonWellKnownBinaryValue 的结果类型必须是二进制类型,而 coordinateSystemId 的必须是整数数值类型。 表达式的结果类型为 Edm.Geometry。

public:
 static System::Data::Common::CommandTrees::DbFunctionExpression ^ GeometryMultiPolygonFromBinary(System::Data::Common::CommandTrees::DbExpression ^ multiPolygonWellKnownBinaryValue, System::Data::Common::CommandTrees::DbExpression ^ coordinateSystemId);
public static System.Data.Common.CommandTrees.DbFunctionExpression GeometryMultiPolygonFromBinary (System.Data.Common.CommandTrees.DbExpression multiPolygonWellKnownBinaryValue, System.Data.Common.CommandTrees.DbExpression coordinateSystemId);
static member GeometryMultiPolygonFromBinary : System.Data.Common.CommandTrees.DbExpression * System.Data.Common.CommandTrees.DbExpression -> System.Data.Common.CommandTrees.DbFunctionExpression
Public Function GeometryMultiPolygonFromBinary (multiPolygonWellKnownBinaryValue As DbExpression, coordinateSystemId As DbExpression) As DbFunctionExpression

参数

multiPolygonWellKnownBinaryValue
DbExpression

提供几何图形多边值的知名二进制表示形式的表达式。

coordinateSystemId
DbExpression

提供几何图形多边值的坐标系统的坐标系统 ID (SRID) 的表达式。

返回

新 DbFunctionExpression 基于指定的值返回新的几何多边形值。

例外

multiPolygonWellKnownBinaryValue coordinateSystemId

multiPolygonWellKnownBinaryValue coordinateSystemId
