TableRowCollection.Count 属性

定义

获取 TableRowTableRowCollection 对象的数目。Gets the number of TableRow objects in the TableRowCollection.

public:
 property int Count { int get(); };
public int Count { get; }
member this.Count : int
Public ReadOnly Property Count As Integer

属性值

Int32

TableRowTableRowCollection 对象的数目。The number of TableRow objects in the TableRowCollection. 默认值为 0。The default is 0.

实现

示例

下面的示例演示如何使用 Count 属性来确定中的行数 TableRowCollectionThe following example demonstrates how to use the Count property to determine the number of rows in the TableRowCollection. 请注意,在此示例中, Rows 的属性 Table 是类的实例 TableRowCollectionNote that in the example, the Rows property of the Table is an instance of the TableRowCollection class.

   void Button_Click_Coord(object sender, EventArgs e) 
   {
       for (int rowNum = 0; rowNum < Table1.Rows.Count; rowNum++)
       {
           for (int cellNum = 0; 
               cellNum < Table1.Rows[cellNum].Cells.Count; cellNum++)
           {
               Table1.Rows[rowNum].Cells[cellNum].Text = 
                   String.Format("({0}, {1})", rowNum, cellNum);
           }            
       }
   }

Sub Button_Click_Coord(sender As Object, e As EventArgs)
    
    Dim rowNum As Integer
    For rowNum = 0 To Table1.Rows.Count - 1
        Dim cellNum As Integer
        For cellNum = 0 To (Table1.Rows(rowNum).Cells.Count) - 1                
            Table1.Rows(rowNum).Cells(cellNum).Text = _
                String.Format("({0}, {1})", rowNum, cellNum)
        Next
    Next
End Sub

注解

使用此属性确定中的行数 TableRowCollectionUse this property to determine the number of rows in the TableRowCollection. Count当循环访问集合以确定上限时,通常会使用属性。The Count property is often used when iterating through the collection to determine the upper bound.
