示例

下面的代码示例演示如何使用类的成员 CodeDirectiveCollection 。

// Creates an empty CodeDirectiveCollection.
CodeDirectiveCollection collection = new CodeDirectiveCollection();

// Adds a CodeDirective to the collection.
collection.Add(new CodeRegionDirective(CodeRegionMode.Start, "Region1"));

// Adds an array of CodeDirective objects to the collection.
CodeDirective[] directives = {
    new CodeRegionDirective(CodeRegionMode.Start,"Region1"),
    new CodeRegionDirective(CodeRegionMode.End,"Region1") };
collection.AddRange(directives);

// Adds a collection of CodeDirective objects to the collection.
CodeDirectiveCollection directivesCollection = new CodeDirectiveCollection();
directivesCollection.Add(new CodeRegionDirective(CodeRegionMode.Start, "Region2"));
directivesCollection.Add(new CodeRegionDirective(CodeRegionMode.End, "Region2"));
collection.AddRange(directivesCollection);

// Tests for the presence of a CodeDirective in the
// collection, and retrieves its index if it is found.
CodeDirective testDirective = new CodeRegionDirective(CodeRegionMode.Start, "Region1");
int itemIndex = -1;
if (collection.Contains(testDirective))
    itemIndex = collection.IndexOf(testDirective);

// Copies the contents of the collection beginning at index 0 to the specified CodeDirective array.
// 'directives' is a CodeDirective array.
collection.CopyTo(directives, 0);

// Retrieves the count of the items in the collection.
int collectionCount = collection.Count;

// Inserts a CodeDirective at index 0 of the collection.
collection.Insert(0, new CodeRegionDirective(CodeRegionMode.Start, "Region1"));

// Removes the specified CodeDirective from the collection.
CodeDirective directive = new CodeRegionDirective(CodeRegionMode.Start, "Region1");
collection.Remove(directive);

// Removes the CodeDirective at index 0.
collection.RemoveAt(0);

        ' Creates an empty CodeDirectiveCollection.
        Dim collection As New CodeDirectiveCollection()
        ' Adds a CodeDirective to the collection.
        collection.Add(New CodeRegionDirective(CodeRegionMode.Start, "Region1"))
        ' Adds an array of CodeDirective objects to the collection.
        Dim directives As CodeDirective() = {New CodeRegionDirective(CodeRegionMode.Start, "Region1"), New CodeRegionDirective(CodeRegionMode.End, "Region1")}
        collection.AddRange(directives)

        ' Adds a collection of CodeDirective objects to the collection.
        Dim directivesCollection As New CodeDirectiveCollection()
        directivesCollection.Add(New CodeRegionDirective(CodeRegionMode.Start, "Region2"))
        directivesCollection.Add(New CodeRegionDirective(CodeRegionMode.End, "Region2"))
        collection.AddRange(directivesCollection)
        ' Tests for the presence of a CodeDirective in the 
        ' collection, and retrieves its index if it is found.
        Dim testDirective = New CodeRegionDirective(CodeRegionMode.Start, "Region1")
        Dim itemIndex As Integer = -1
        If collection.Contains(testDirective) Then
            itemIndex = collection.IndexOf(testDirective)
        End If
        ' Copies the contents of the collection beginning at index 0 to the specified CodeDirective array.
        ' 'directives' is a CodeDirective array.
        collection.CopyTo(directives, 0)
        ' Retrieves the count of the items in the collection.
        Dim collectionCount As Integer = collection.Count
        ' Inserts a CodeDirective at index 0 of the collection.
        collection.Insert(0, New CodeRegionDirective(CodeRegionMode.Start, "Region1"))
        ' Removes the specified CodeDirective from the collection.
        Dim directive = New CodeRegionDirective(CodeRegionMode.Start, "Region1")
        collection.Remove(directive)
        ' Removes the CodeDirective at index 0.
        collection.RemoveAt(0)
    
    End Sub
End Class

注解

该 CodeDirectiveCollection 类提供一个简单的集合对象，可用于存储一组 CodeDirective 对象。
