Breakpoints.Item 方法

傳回在 Breakpoints 集合中的 Breakpoint 物件。

命名空間：  EnvDTE
組件：  EnvDTE (在 EnvDTE.dll 中)

語法

'宣告
Function Item ( _
    index As Object _
) As Breakpoint

Breakpoint Item(
    Object index
)

Breakpoint^ Item(
    [InAttribute] Object^ index
)

abstract Item : 
        index:Object -> Breakpoint 

function Item(
    index : Object
) : Breakpoint

參數

• index
  型別：System.Object
  必要項。要傳回之 Breakpoint 物件的索引。

傳回值

型別：EnvDTE.Breakpoint
Breakpoint 物件。

備註

如果集合無法找到對應於索引值的物件，Item 方法就會擲回 ArgumentException 例外狀況。

範例

下列範例示範如何使用 Item 方法。

若要測試這個方法：

1. 開啟目標專案並執行增益集。

public static void Item(DTE dte)
{
    // Setup debug Output window.
    Window w = (Window)dte.Windows.Item(EnvDTE.Constants.vsWindowKindOutput);
    w.Visible = true;
    OutputWindow ow = (OutputWindow)w.Object;
    OutputWindowPane owp = ow.OutputWindowPanes.Add("Item Method Test: ");
    owp.Activate();

    // dte is a reference to the DTE object passed to you by the
    // OnConnection method that you implement when you create an add-in.
    EnvDTE.Debugger debugger = (EnvDTE.Debugger)dte.Debugger;
    debugger.Breakpoints.Add("","Target001.cs", 13, 1, "", 
                             EnvDTE.dbgBreakpointConditionType.dbgBreakpointConditionTypeWhenTrue, 
                             "C#","", 0, "", 0, EnvDTE.dbgHitCountType.dbgHitCountTypeNone);
    debugger.Breakpoints.Add("","Target001.cs", 15, 1, "", 
                             EnvDTE.dbgBreakpointConditionType.dbgBreakpointConditionTypeWhenTrue, 
                             "C#","", 0, "", 0, EnvDTE.dbgHitCountType.dbgHitCountTypeNone);

    owp.OutputString("\nNumber of Breakpoints: " + debugger.Breakpoints.Count);
    owp.OutputString("\nEdition of the environment: " + 
                     debugger.Breakpoints.DTE.Edition);
    owp.OutputString("\nParent's Current Mode: " + 
                     debugger.Breakpoints.Parent.CurrentMode);
    owp.OutputString("\nFirst breakpoint is on line " + 
                     debugger.Breakpoints.Item(1).FileLine + ".");
    owp.OutputString("\nSecond breakpoint is on line " + 
                     debugger.Breakpoints.Item(2).FileLine + ".");
}

Shared Sub Item(ByRef dte As EnvDTE.DTE)
    Dim str As String
    dte.Debugger.Breakpoints.Add("", "Target001.cs", 13, 1, "", _
                                 EnvDTE.dbgBreakpointConditionType.dbgBreakpointConditionTypeWhenTrue, _
                                 "C#", "", 0, "", 0, EnvDTE.dbgHitCountType.dbgHitCountTypeNone)
    dte.Debugger.Breakpoints.Add("", "Target001.cs", 15, 1, "", _
                                 EnvDTE.dbgBreakpointConditionType.dbgBreakpointConditionTypeWhenTrue, _
                                 "C#", "", 0, "", 0, EnvDTE.dbgHitCountType.dbgHitCountTypeNone)
    str = "Number of Breakpoints: " + dte.Debugger.Breakpoints.Count.ToString() + vbCrLf
    str += "Edition of the environment: " + dte.Debugger.Breakpoints.DTE.Edition + vbCrLf
    str += "Parent's Current Mode: " + dte.Debugger.Breakpoints.Parent.CurrentMode.ToString() + vbCrLf
    str += "First breakpoint is on line " + dte.Debugger.Breakpoints.Item(1).FileLine.ToString() + "." + vbCrLf
    str += "Second breakpoint is on line " + dte.Debugger.Breakpoints.Item(2).FileLine.ToString() + "." + vbCrLf
    MessageBox.Show(str, "Item Method Test")
End Sub
