SerializationInfo.GetUInt64(String) 方法

定義

重要

此 API 不符合 CLS 規範。

SerializationInfo 存放區擷取 64 位元不帶正負號的整數值。Retrieves a 64-bit unsigned integer value from the SerializationInfo store.

public:
 System::UInt64 GetUInt64(System::String ^ name);
[System.CLSCompliant(false)]
public ulong GetUInt64 (string name);
member this.GetUInt64 : string -> uint64
Public Function GetUInt64 (name As String) As ULong

參數

name
String

與要擷取的值相關聯的名稱。The name associated with the value to retrieve.

傳回

name 建立關聯的 64 位元不帶正負號的整數。The 64-bit unsigned integer associated with name.

屬性

例外狀況

namenullname is null.

name 建立關聯的值無法轉換為 64 位元不帶正負號的整數。The value associated with name cannot be converted to a 64-bit unsigned integer.

在目前的執行個體中找不到具有指定名稱的項目。An element with the specified name is not found in the current instance.

備註

如果值是64位不帶正負號的整數, 或可以轉換成一個, 則會傳回該值;否則, InvalidCastException就會擲回。If the value is a 64-bit unsigned integer, or can be converted to one, that value is returned; otherwise, a InvalidCastException is thrown. 所有的轉換都是由IFormatterConverter與這個SerializationInfo相關聯的所完成。All conversions are done by the IFormatterConverter associated with this SerializationInfo.
