示例

以下示例演示如何创建主键字典。

private RouteValueDictionary GetRouteValues(MetaTable table, object row) {  
    RouteValueDictionary routeValues = GetRouteValues();  
    foreach (var pk in table.GetPrimaryKeyDictionary(row)) {  
        routeValues[pk.Key] = pk.Value;  
    }  
    return routeValues;  
}   

Private Function GetRouteValues(ByVal table As MetaTable, _  
        ByVal row As Object) As RouteValueDictionary   
    Dim routeValues As RouteValueDictionary = GetRouteValues()   
    For Each pk In table.GetPrimaryKeyDictionary(row)   
        routeValues(pk.Key) = pk.Value   
    Next   
    Return routeValues   
End Function
