fieldInfo.setValue（）：类型的对象＆＃x27; system.string＆＃x27;无法转换为type＆＃x27; system.int32＆＃x27;

Question

程序逻辑：

• 在C＃程序中为雇员定义一些默认值
• ，读取有关不同员工的XML文件
• 使用反思浏览defaultAttributes的所有字段< /code>类，
• 如果字段名称作为员工的XML节点中的属性存在，则用属性值

雇员defaultAttributes class

public class DefaultAttributes
{
    public string EmployeeName = "XYZ";
    public int[] ProjectCodes = new int[] { 1, 1 };
    public string city = "Munich";
}

xml file：

   <TopNode Id="A">
      <MiddleNode EmployeeName="John">
         <InnerMostNode Age="46" Average="88.15" ProjectCodes="46 112" City="Berlin">            
         </InnerMostNode>
      </MiddleNode>
      <MiddleNode EmployeeName="Claudia">
         <InnerMostNode Age="50" Average="96.58" ProjectCodes="9 510">            
         </InnerMostNode>
      </MiddleNode>
   </TopNode>

使用反射来覆盖默认值：

    private void OverrideAttribites(XmlNode xmlNode, DefaultAttributes nodeAttributes)
    {
        //Traverse through all fileds of DefaultAttributes class
        FieldInfo[] fieldsOfDefaultAttributesclass = typeof(DefaultAttributes).GetFields(BindingFlags.Public | BindingFlags.Instance);
        foreach (var field in fieldsOfDefaultAttributesclass)
        {
            // Check if the "field" is present in the attributes of the current XML node
            string fieldName = field.Name;
            if (xmlNode.Attributes[fieldName] is not null) //i.e. field is present in the Attributes list
            {
                var attValue = xmlNode.Attributes[fieldName].Value;

                if (attValue.Contains(' ')) //i.e. attribute value should be stored in an array type
                {
                    if (!fieldName.Contains('['))
                    {
                        throw new Exception("Field type is not an array type but the XML attribute value contains an array");
                    }

                    //Set Array Value
                }
                else
                {
                    //PROBLEM: THIS LINE THROWS EXCEPTION !!!!!
                    field.SetValue(nodeAttributes, xmlNode.Attributes[fieldName].Value);
                }
            }
        }
    }

问题：我的XML文件中的属性值String格式。我如何使用属性的值以通用方式设置字段值（字段可以是int， double ，，int [ ]等）？
