Dim dtsContainer As DtsContainer 
Dim property As IDTSPropertiesProvider 
Dim propertyName As String

bool EditPropertyExpression(
    IWin32Window parentWindow,
    DtsContainer dtsContainer,
    IDTSPropertiesProvider property,
    string propertyName
)

bool EditPropertyExpression(
    IWin32Window^ parentWindow, 
    DtsContainer^ dtsContainer, 
    IDTSPropertiesProvider^ property, 
    String^ propertyName
)

abstract EditPropertyExpression : 
        parentWindow:IWin32Window * 
        dtsContainer:DtsContainer * 
        property:IDTSPropertiesProvider * 
        propertyName:string -> bool

function EditPropertyExpression(
    parentWindow : IWin32Window, 
    dtsContainer : DtsContainer, 
    property : IDTSPropertiesProvider, 
    propertyName : String
) : boolean

参数

• parentWindow
  类型：System.Windows.Forms.IWin32Window
  The IWin32Window handle to the Windows form from which the Expression Builder dialog box is invoked.

• dtsContainer
  类型：Microsoft.SqlServer.Dts.Runtime.DtsContainer
  The DtsContainer that defines the scope for package variables that can be used in the expression.

• property
  类型：Microsoft.SqlServer.Dts.Runtime.IDTSPropertiesProvider
  The IDTSPropertiesProvider that represents the property to which the expression is assigned.

• propertyName
  类型：System.String
  The name of the property to which the expression is assigned.

返回值

类型：System.Boolean
true if the expression has changed; otherwise, false.

注释

When the expression is a property expression, the EditPropertyExpression method is simpler to use than the EditExpression method. The EditPropertyExpression method determines the return type of the expression from the data type of the property and assigns the expression to the property for you. However, you can also use the EditExpression method whenever you want to let the user create or modify an expression.
