创建一个 DbFunctionExpression ，该函数使用指定的参数调用规范“GeographyCollectionFromBinary”函数。 geographyCollectionWellKnownBinaryValue 必须具有二进制结果类型，而 coordinateSystemId 必须具有整数数值结果类型。表达式的结果类型为 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
