[英]Bind object properties with string dynamically
我有一堂課
public class SearchModel
{
public string Locations { get; set; }
public string City { get; set; }
public string Address { get; set; }
public string MaxRecord { get; set; }
public string PageSize { get; set; }
....
....
Approx 80 properties
}
我有一個查詢字符串,例如"my location_Locations/new york_City/city street_Address/200_MaxRecord/20_PageSize"
上面的字符串包含類SearchModel
的確切屬性名稱。 現在我想做以下事情:
SearchModel model = new SearchModel();
string[] Parameters = "my location_Locations/new york_City/city street_Address/200_MaxRecord/20_PageSize".Split('/');
foreach (string item in Parameters)
{
string[] value=item.Split('_');
model.value[1] = value[0];
}
將以下代碼添加到您的課程中
public class SearchModel
{
public object this[string propertyName]
{
get{
Type myType = typeof(MyClass);
PropertyInfo myPropInfo = myType.GetProperty(propertyName);
return myPropInfo.GetValue(this, null);
}
set{
Type myType = typeof(SearchModel);
PropertyInfo myPropInfo = myType.GetProperty(propertyName);
switch (myPropInfo.PropertyType.Name)
{
case "Int32":
myPropInfo.SetValue(this, Convert.ToInt32(value), null);
break;
case "Int64":
myPropInfo.SetValue(this, Convert.ToInt64(value), null);
break;
case "Boolean":
myPropInfo.SetValue(this, Convert.ToBoolean(value), null);
break;
case "DateTime":
myPropInfo.SetValue(this, Convert.ToDateTime(value), null);
break;
case "String":
myPropInfo.SetValue(this, value.ToString(), null);
break;
default:
myPropInfo.SetValue(this, value, null);
break;
}
}
}
}
和您修改的代碼
SearchModel model = new SearchModel();
string[] Parameters = "my location_Locations/new york_City/city street_Address/200_MaxRecord/20_PageSize".Split('/');
foreach (string item in Parameters)
{
string[] value= item.Split('_');
// I changed this line
model[value[1]] = value[0];
}
要么
SearchModel model = new SearchModel();
string[] Parameters = "my location_Locations/new york_City/city street_Address/200_MaxRecord/20_PageSize".Split('/');
foreach (string item in Parameters)
{
string[] value= item.Split('_');
PropertyInfo propertyInfo = model.GetType().GetProperty(value[1]);
propertyInfo.SetValue(model, Convert.ChangeType(value[0], propertyInfo.PropertyType),
}
對於不區分大小寫的:
model.GetType().GetProperty(value[1], BindingFlags.IgnoreCase | BindingFlags.Public | BindingFlags.Instance )
