建立 DbFunctionExpression 一個，能呼叫典型的「GeographyMultiLineFromBinary」函式，並附上指定的參數。 multiLineWellKnownBinaryValue 必須有二元結果型別，而 coordinateSystemId 必須有整數數值結果型別。該表達式的結果類型為 Edm.地理。

public:
 static System::Data::Common::CommandTrees::DbFunctionExpression ^ GeographyMultiLineFromBinary(System::Data::Common::CommandTrees::DbExpression ^ multiLineWellKnownBinaryValue, System::Data::Common::CommandTrees::DbExpression ^ coordinateSystemId);

public static System.Data.Common.CommandTrees.DbFunctionExpression GeographyMultiLineFromBinary(System.Data.Common.CommandTrees.DbExpression multiLineWellKnownBinaryValue, System.Data.Common.CommandTrees.DbExpression coordinateSystemId);

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

Public Function GeographyMultiLineFromBinary (multiLineWellKnownBinaryValue As DbExpression, coordinateSystemId As DbExpression) As DbFunctionExpression
