String.GetTypeCode 方法

定义

命名空间:

System

程序集:

System.Runtime.dll

Source:

String.cs

返回 String 类的 TypeCode。

public:
 virtual TypeCode GetTypeCode();

public TypeCode GetTypeCode ();

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

Public Function GetTypeCode () As TypeCode

返回

TypeCode

枚举常数 String。

实现

GetTypeCode()

示例

以下示例显示 类型的 TypeCode 枚举常量 String 。

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

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.
