拼写CAML查询的小工具

是不是感觉写一个CAML的查询有点麻烦? 尤其是在写复杂查询的时候. 在这里跟大家分享一个codeplex上的工具, 专门用来帮你拼CAML查询字符串的.

使用步骤:

1. 下载CAMLHelper.dll

2. 新建一个C#的Console Application.

3. 添加对该dll的引用.

4. 粘贴下面的示例代码.

 

using System;

using System.Collections.Generic;

using System.Text;

using StooRob.CAMLHelper.CAML;



namespace CAMLHelperTest

{

    class Program

    {

        static void Main(string[] args)

        {

            CAMLManager target = new CAMLManager(

                new QueryGroup(

                    "Title", 

                    Types.FieldTypes.Text, 

                    Types.QueryTypes.Eq, 

                    "List Item Title"

                )

            );



            target.QueryGroups.Add(

                new QueryGroup(

                    Types.FieldRefTypes.ID, 

                    "{D562C8AC-457A-446b-84D6-2FA26FAABED7}", 

                    Types.FieldTypes.YesNo, 

                    Types.QueryTypes.Neq, 

                    "true"

                )

            );



            target.OrderBy.Add(new OrderBy("Title", false));



            target.ViewFields.Add(new ViewField("Title"));

            target.ViewFields.Add(

                new ViewField(

                    "{D562C8AC-457A-446b-84D6-2FA26FAABED7}", 

                    Types.FieldRefTypes.ID

                )

            );



            target.RowLimit = 100;



            string camlQuery = target.GetFullCAML();



            Console.WriteLine(camlQuery);

            Console.ReadLine();

        }

    }

}

 

程序输出结果(未整理):

<Where><And><Eq><FieldRef Name="Title" /><Value Type="Text">List Item Title</Val
ue></Eq><Neq><FieldRef ID="{D562C8AC-457A-446b-84D6-2FA26FAABED7}" /><Value Type
="YesNo">true</Value></Neq></And></Where><OrderBy><FieldRef Name="Title" Ascendi
ng="False" /></OrderBy><ViewFields><FieldRef Name="Title" /><FieldRef ID="{D562C
8AC-457A-446b-84D6-2FA26FAABED7}" /></ViewFields><RowLimit>100</RowLimit>

 

整理后看起来如下:

<Where>

  <And>

    <Eq>

      <FieldRef Name="Title" />

      <Value Type="Text">List Item Title</Value>

    </Eq>

    <Neq>

      <FieldRef ID="{D562C8AC-457A-446b-84D6-2FA26FAABED7}" />

      <Value Type="YesNo">true</Value>

    </Neq>

  </And>

</Where>

<OrderBy>

  <FieldRef Name="Title" Ascending="False" />

</OrderBy>

<ViewFields>

  <FieldRef Name="Title" />

  <FieldRef ID="{D562C8AC-457A-446b-84D6-2FA26FAABED7}" />

</ViewFields>

<RowLimit>100</RowLimit>

 

注: codeplex上有该工具的源代码. 可以供学习参考之用.
