Public Overridable Function ToString As String
Dim instance As Object Dim returnValue As String returnValue = instance.ToString
public virtual string ToString ()
public: virtual String^ ToString ()
public String ToString ()
public function ToString () : String
此方法返回区分区域性的可读字符串。例如，对于值为零的 Double 类的实例，Double.ToString 的实现可能返回“0.00”或“0,00”，具体取决于当前的 UI 区域性。
默认实现返回 Object 的类型的完全限定名。
下面的代码示例说明 ToString 返回的内容。
Imports System Public Class Sample Sub Method() ' Prints out: "System.Object" Dim o As New Object() Console.WriteLine(o.ToString()) End Sub 'Method End Class 'Sample
using System; public class Sample { void Method() { // Prints out: "System.Object" Object o = new Object(); Console.WriteLine (o.ToString()); } }
#using <System.DLL> using namespace System; ref class Sample { private: void Method() { // Prints out: "System.Object" Object^ o = gcnew Object; Console::WriteLine( o->ToString() ); } };
import System.*; public class Sample { void Method() { // Prints out: "System.Object" Object o = new Object(); Console.WriteLine(o.ToString()); } //Method } //Sample
