String.IConvertible.GetTypeCode 方法

定義

命名空間:

System

組件:

System.Runtime.dll

針對 String 類別傳回 TypeCode。

 virtual TypeCode System.IConvertible.GetTypeCode() = IConvertible::GetTypeCode;

TypeCode IConvertible.GetTypeCode ();

abstract member System.IConvertible.GetTypeCode : unit -> TypeCode
override this.System.IConvertible.GetTypeCode : unit -> TypeCode

Function GetTypeCode () As TypeCode Implements IConvertible.GetTypeCode

傳回

TypeCode

列舉常數 String。

實作

GetTypeCode()

範例

下列範例會顯示 TypeCode 型別的 String 列舉常數。

// Sample for String.GetTypeCode()
using namespace System;
int main()
{
   String^ str = "abc";
   TypeCode tc = str->GetTypeCode();
   Console::WriteLine( "The type code for '{0}' is {1}, which represents {2}.", str, tc.ToString( "D" ), tc.ToString( "F" ) );
}

/*
This example produces the following results:
The type code for 'abc' is 18, which represents String.
*/

// Sample for String.GetTypeCode()
using System;

class Sample
{
    public static void Main()
    {
    String str = "abc";
    TypeCode tc = str.GetTypeCode();
    Console.WriteLine("The type code for '{0}' is {1}, which represents {2}.",
                         str, tc.ToString("D"), tc.ToString("F"));
    }
}
/*

*/

let str = "abc"
let tc = str.GetTypeCode()
printfn $"""The type code for '{str}' is {tc.ToString "D"}, which represents {tc.ToString "F"}."""
// This example produces the following results:
//     The type code for 'abc' is 18, which represents String.
