需求:定义一个文本框,defaultValue = CGC,长度不能小于等于5

步骤如下:

1. 创建Sharepoint2010项目(类库)
2. 添加引用(microsoft.sharepoint.dll)
3. 写代码(看代码你就懂了,比较简单)及编写xml
4. 部署(把dll拷贝到gac里,再把xml文件拷到C:\Program Files\Common Files\Microsoft Shared\Web Server Extensions\14\TEMPLATE\XML下,再重启IIS)就可以了.

cs代码如下:

using System;
using System.Collections.Generic;
using System.Linq;
using System.Text;
using Microsoft.SharePoint;

namespace SharepointField
{
    public class FirstField:SPFieldText
    {
        public FirstField(SPFieldCollection fields,string fieldName): base(fields, fieldName)
        { 
            
        }

        public FirstField(SPFieldCollection fields, string fieldName, string displayName):base(fields,fieldName,displayName)
        { 
            
        }

        public override string DefaultValue
        {
            get
            {
                return "CGC";
            }
        }
        public override string GetValidatedString(object value)
        {
            if (value.ToString().Length <= 5)
            {
                throw new SPFieldValidationException("长度必须大于5");
            }

            return base.GetValidatedString(value);
        }

    }

}

 xml文件(fldtypes_FirstField.xml必须fldtypes_开头)如下:

<?xml version="1.0" encoding="utf-8" ?>
<FieldTypes>
  <FieldType>
    <Field Name="TypeName">FirstField</Field>
    <Field Name="ParentType">Text</Field>
    <Field Name="TypeDisplayName">FirstFieldDisplay</Field>
    <Field Name="TypeShortDescription">FirstFieldDesc</Field>
    <Field Name="UserCreatable">TRUE</Field>
    <Field Name="FieldTypeClass">SharepointField.FirstField,SharepointField, Version=1.0.0.0, Culture=neutral, PublicKeyToken=b2db6aae38d37e8a</Field>
  </FieldType>
</FieldTypes>

先做个简单的,后续继续研究...
