如何使用C＃来获得在SharePoint的多行文本字段值 [英] How to get the text value from Multiline text field in sharepoint using C#

问题描述

我试过这个程式码：

  using（SPSite oSite = new SPSite（http：// omar：2020 / Lists /Calendar1/AllItems.aspx））
 {
 using（SPWeb oWeb = oSite.OpenWeb（））
 {
 SPList oList = oWeb.Lists [Calendar]; 
 SPListItem item = oList.GetItemById（7）; 
 
 txtArea_desc.InnerText = item [Description]。ToString（）; 
 
} 
} 
  

但它给了我class =

有任何建议吗？

解决方案内容类型具有以下声明：

>

 < Field ID ={9da97a8a-1da5-4a77-98d3-4bc10456e700}
 Type =Note
 RichText = TRUE
 Name =Comments
 Group =_ Hidden
 DisplayName =$ Resources：core，Comments;
 Sortable =FALSE
 SourceID = http://schemas.microsoft.com/sharepoint/v3
 StaticName =Comments> 
< / Field> 
  

由于 RichText 属性设置为true，它的值包含html内容。

使用 SPField.GetFieldValueAsText方法以获取纯文本的字段值。

示例 p>

  using（var site = new SPSite（siteUrl））
 {
 using（var web = site.OpenWeb （））
 {
 var list = web.Lists.TryGetList（listTitle）; 
 var item = list.GetItemById（itemId）; 
 var eventDescField = list.Fields.GetFieldByInternalName（Description）; 
 var eventDesc = item [eventDescField.Id]; 
 var eventDescText = eventDescField.GetFieldValueAsText（eventDesc）; 
 
} 
} 
  

I tried this code:

using (SPSite oSite = new SPSite("http://omar:2020/Lists/Calendar1/AllItems.aspx"))
{
    using (SPWeb oWeb = oSite.OpenWeb())
    {
        SPList oList = oWeb.Lists["Calendar"];
        SPListItem item = oList.GetItemById(7);

        txtArea_desc.InnerText = item["Description"].ToString();

    }
}

But it gave me "class="ExternalClassD6E6296DE90F457892C156ABE9631AC6Hello" in the TextArea.

Any suggestions please?

解决方案

Description field in Event content type has the following declaration:

<Field ID="{9da97a8a-1da5-4a77-98d3-4bc10456e700}"
    Type="Note"
    RichText="TRUE"
    Name="Comments"
    Group="_Hidden"
    DisplayName="$Resources:core,Comments;"
    Sortable="FALSE"
    SourceID="http://schemas.microsoft.com/sharepoint/v3"
    StaticName="Comments">
</Field> 

Since RichText attribute is set to true, it's value contains html content.

Use SPField.GetFieldValueAsText Method to get the field value as plain text.

Example

using (var site = new SPSite(siteUrl))
{
    using (var web = site.OpenWeb())
    {
        var list = web.Lists.TryGetList(listTitle);
        var item = list.GetItemById(itemId);
        var eventDescField = list.Fields.GetFieldByInternalName("Description");
        var eventDesc = item[eventDescField.Id];
        var eventDescText = eventDescField.GetFieldValueAsText(eventDesc);

    }
}
