将字符串列表绑定到WPF ListView返回BindingExpression路径错误

Question

I've two string lists declared as below:

Config.cs:

public class AgentSkills 
{
  public List<string> agentSkillsNameList=new List<string>();
  public List<string> agentSkillsLvlList=new List<string>();
}

I retrieved the strings from an XML and added them to the lists as below:

Config.cs:

foreach (XmlNode skillNameNode in skillNameNodeList) 
{
  agentSkills.agentSkillsNameList.Add(skillNameNode.Attributes["value"].Value);
}

foreach (XmlNode skillLevelNode in skillLevelNodeList) 
{
  agentSkills.agentSkillsLvlList.Add(skillLevelNode.Attributes["value"].Value);
}

Then, I passed those list and bound them into a listview like this:

Info.cs:

Config.AgentSkills abc = new Config.AgentSkills();

this.AInfoLv.Items.Add(new { Label=" " + abc.agentSkillsNameList, Value=" " + abc.agentSkillsLvlList });

But it returns errors as below:

System.Windows.Data Error:40:BindingExpression path error:'Value' property not found on'object'''<>f__AnonymousType0`1' (HashCode=2053256737)'. BindingExpression:Path=Value;

Is it ok to bind string lists into a listview in wpf? If can't, is there any suggestion on this problem?

Answer 1

But you aren't binding a list of strings to a ListView , you are binding an IEnumerable<String> to a TextBlock.Text field, when it is expecting a String as you can see in the errors.

The fastest way to solve your problem is to change the line to

this.AInfoLv.Items.Add(new { 
   Label=" " + string.Join(", ", abc.agentSkillsNameList), 
   Value=" " + string.Join(", ", abc.agentSkillsLvlList) 
});
