MimePartCollection.IndexOf(MimePart) 方法

定义

命名空间:

System.Web.Services.Description

程序集:

System.Web.Services.dll

搜索指定的 MimePart，并返回集合中第一个匹配项的索引（从零开始）。

public:
 int IndexOf(System::Web::Services::Description::MimePart ^ mimePart);

public int IndexOf (System.Web.Services.Description.MimePart mimePart);

member this.IndexOf : System.Web.Services.Description.MimePart -> int

Public Function IndexOf (mimePart As MimePart) As Integer

参数

mimePart

MimePart

要为其搜索 MimePart 的 MimePartCollection。

返回

Int32

32 位带符号整数。

示例

以下示例演示 了 方法的典型用法 IndexOf 。

MimeMultipartRelatedBinding^ myMimeMultipartRelatedBinding = nullptr;
IEnumerator^ myIEnumerator = myOutputBinding->Extensions->GetEnumerator();
while ( myIEnumerator->MoveNext() )
   myMimeMultipartRelatedBinding = (MimeMultipartRelatedBinding^)myIEnumerator->Current;

// Create an instance of 'MimePartCollection'.
MimePartCollection^ myMimePartCollection = gcnew MimePartCollection;
myMimePartCollection = myMimeMultipartRelatedBinding->Parts;
Console::WriteLine( "Total number of mimepart elements in the collection initially  is: {0}", myMimePartCollection->Count );

// Get the type of first 'Item' in collection.
Console::WriteLine( "The first object in collection is of type: {0}", myMimePartCollection[ 0 ] );
MimePart^ myMimePart1 = gcnew MimePart;

// Create an instance of 'MimeXmlBinding'.
MimeXmlBinding^ myMimeXmlBinding1 = gcnew MimeXmlBinding;
myMimeXmlBinding1->Part = "body";
myMimePart1->Extensions->Add( myMimeXmlBinding1 );

//  a mimepart at first position.
myMimePartCollection->Insert( 0, myMimePart1 );
Console::WriteLine( "Inserting a mimepart object..." );

// Check whether 'Insert' was successful or not.
if ( myMimePartCollection->Contains( myMimePart1 ) )
{
   // Display the index of inserted 'MimePart'.
   Console::WriteLine( "'MimePart' is successfully inserted at position: {0}", myMimePartCollection->IndexOf( myMimePart1 ) );
