Above is an enumerated list, how to read it? Using a DDR to bind it?

Copy Code code as follows:

Ddltype.displaymember = "Value";
Ddltype.valuemember = "Key";
Ddltype.datasource = Commonfunctions.getenumitems (typeof (Appenum.pointlogtype), false);
Ddltype.selectedvalue = 25; Default value

Here is the Getenumitems method in Commonfunctions:

Copy Code code as follows:

<summary>
Gets a list of all the items contained by the enumeration type.
</summary>
<param name= "Enumtype" > Enumeration type </param>
<param name= "Withall" > contains "all" </param>
<returns></returns>
public static list<enumitem> Getenumitems (Type enumtype, bool Withall)
{
list<enumitem> list = new list<enumitem> ();

if (Enumtype.isenum!= true)
{
Not an enumeration type
throw new InvalidOperationException ();
}

Include all option
if (Withall = = True)
List. ADD (New Enumitem (Appconst.intnull, "all"));

Get type information for attribute description
Type typedescription = typeof (DescriptionAttribute);

Gets the field information for the enumeration (because the value of the enumeration is actually the value of a static field)
system.reflection.fieldinfo[] fields = Enumtype.getfields ();

Retrieve all Fields
foreach (FieldInfo field in fields)
{
To filter out a value that is not enumerated, the source type of the enumeration is recorded
if (field. Fieldtype.isenum = = False)
Continue

Get the value of an enumeration by the name of the field
int value = (int) enumtype.invokemember (field. Name, Bindingflags.getfield, NULL, NULL, NULL);
string text = String. Empty;

To get all the custom attributes for this field, just look for the description feature
object[] arr = field. GetCustomAttributes (Typedescription, true);
if (arr. Length > 0)
{
Because the description custom attribute does not allow duplicates, it takes only the first
DescriptionAttribute AA = (DescriptionAttribute) arr[0];

To obtain a descriptive value for an attribute
Text = AA. Description;
}
Else
{
If there is no description of the feature, then the field name in English is displayed
Text = field. Name;
}
List. ADD (New Enumitem (value, text));
}

return list;
}
public class Enumitem
{
Private Object M_key;
Private object m_value;

public Object Key
{
get {return m_key;}
set {M_key = value;}
}

public Object Value
{
get {return m_value;}
set {m_value = value;}
}

Public Enumitem (Object _key, Object _value)
{
M_key = _key;
M_value = _value;
}
}
