TableRowCollection.Count 属性
定义
获取 TableRow 中 TableRowCollection 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
TableRow 中 TableRowCollection 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 TableRowCollection 。The 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 TableRowCollection 。Note 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 TableRowCollection 。Use 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.
