PackageInfos.Contains(Object) 方法

定义

命名空间:

Microsoft.SqlServer.Dts.Runtime

程序集:

Microsoft.SqlServer.ManagedDTS.dll

返回一个布尔值，该值指示是否可以使用名称、索引、GUID 或说明参数从集合中检索对象。

public:
 bool Contains(System::Object ^ index);

public bool Contains (object index);

member this.Contains : obj -> bool

Public Function Contains (index As Object) As Boolean

参数

index

Object

集合中要匹配的对象的名称、索引、GUID 或说明。

返回

Boolean

如果可以使用语法 PackageInfos[index] 从集合中检索对象，则为 true。

示例

下面的代码示例返回集合中第一个包的名称。

            PackageInfos pInfos = app.GetDtsServerPackageInfos(@"File System", "YOURSERVER");  
            Console.WriteLine("Number of Packages {0}", pInfos.Count.ToString());  

            if (pInfos.Contains(0))  
            {  
                Console.WriteLine("Package {0} found ", pInfos[0].Name);

            else

                Console.WriteLine("Package cannot be found using Contains");  
            }  
         }  
    }  
}

            app.SaveToDtsServer(p1, Nothing, "File System\myp1Package", "YOURSERVER")  
            app.SaveToDtsServer(p2, Nothing, "File System\myp2Package", "YOURSERVER")  

            Dim pInfos As PackageInfos =  app.GetDtsServerPackageInfos("File System","YOURSERVER")   
            Console.WriteLine("Number of Packages {0}", pInfos.Count.ToString())  

            If pInfos.Contains(0) Then  
                Console.WriteLine("Package {0} found ", pInfos(0).Name)  
            Else   
                Console.WriteLine("Package cannot be found using Contains")  
            End If  
        End Sub  
    End Class

示例输出：
