Template maintenance-template parsing and template maintenance Parsing

The template Parsing is mainly about the main template parsing.

First, let's talk about the business logic. First, click the node of the tree, pay the code of the tree to the material code, and then query the main template (including the main template ID and main template information) through the material code) and sub-templates (without {} information );

If there is information in the form of {}, we pay the master template ID and master template information to the String parameter and upload it to the foreground. At the front-end, first determine whether the passed String parameter is null. If it is null, there is no master template. Otherwise, the sub-template information is loaded.

Parse the main template:

Step 1:

The main template information obtained from the above logic is {: diesel locomotive, 0; electric locomotive, 1; passenger car, 2; freight car, 3; EMU, 4; to be decommissioned, 5; other obsolete materials, 9.

Step 2:

We split it.
Define a datatable and assign two fields to it: one ID and one Name.

Step 3:

Cut the string, first put the first two characters {: delete method: Substring (2, Smatlcate. Length-2)

The string is changed to a diesel locomotive, 0; electric locomotive, 1; passenger car, 2; freight car, 3; EMU, 4; to be decommissioned, 5; other obsolete materials, 9 ;}

Then we can remove the final} as follows:. Split ('}') [0]. Trim ()
 
The string is changed to a diesel locomotive, 0; electric locomotive, 1; passenger car, 2; freight car, 3; EMU, 4; to be decommissioned, 5; other obsolete materials, 9;
 
We will remove the last semicolon as follows: TrimEnd (';')
 
The string is changed to a diesel locomotive, 0; electric locomotive, 1; passenger car, 2; freight car, 3; EMU, 4; to be decommissioned, 5; other obsolete materials, 9

Step 3:

In this way, we can convert the array: string [] strArr = Smatlcate. Split (';'). This is an array conversion using a semicolon separator.

Step 4:
Finally, we can assign values to the previously defined able (including two sections) cyclically. The method is as follows:


DataRow dr = dt_ChildTemplets.NewRow ();
Dr ["ID"] = strArr [I]. Split (',') [1]. Trim ();
Dr ["NAME"] = "series:" + strArr [I]. split (',') [0]. trim () + "," + strArr [I]. split (',') [1]. trim ();

Finally, we successfully uploaded the array information to the able.

If you bind dt to the drop-down list, you can assign values.

There will be blog posts about subtemplate parsing and template testing in the future.
