ToString 方法

Returns the Open Geospatial Consortium (OGC) Well-Known Text (WKT) representation of a SqlGeometry instance augmented with any Z (elevation) and M (measure) values carried by the instance.

命名空间：  Microsoft.SqlServer.Types
程序集：  Microsoft.SqlServer.Types（在 Microsoft.SqlServer.Types.dll 中）

语法

声明
<SqlMethodAttribute(IsDeterministic := True, IsPrecise := False)> _
Public Overrides Function ToString As String
用法
Dim instance As SqlGeometry
Dim returnValue As String

returnValue = instance.ToString()

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public override string ToString()

[SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)]
public:
virtual String^ ToString() override

[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)>]
abstract ToString : unit -> string 
[<SqlMethodAttribute(IsDeterministic = true, IsPrecise = false)>]
override ToString : unit -> string 

public override function ToString() : String

返回值

类型：System. . :: . .String
A string value containing the WKT representation of the calling instance.

注释

This method will return the string "Null" when called on null instances.
