C＃部分类返回null

Question

我正在尝试创建填充信息路径模板并将其上传到Sharepoint。我一直遵循以下说明https://www.codeproject.com/Articles/33228/Programmatically-create-a-browser-enabled-InfoPath

这是我生成的代码的一个示例

公共局部类myFields：

...
public partial class myFields
{ 
    private General_Information general_InformationField;
    ...
    public General_Information General_Information
    {
        get
        {
            return this.general_InformationField;
        }
        set
        {
            this.general_InformationField = value;
        }
    }
    ...
}
...

公共局部类General_Information

public partial class General_Information
{

    private string wellField;
    ...

    public string Well
    {
        get
        {
            return this.wellField;
        }
        set
        {
            this.wellField = value;
        }
    }
    ...

说明填充数据：

myFields fields = new myFields();
fields.Name = "Joe";
fields.Surname = "Blogs";

当我尝试按照网站中的示例进行操作时：

myFields fields = new myFields();
fields.General_Information.Well = "name";

我收到一条错误消息，说 myFields.General_Information。** get **返回null。

执行此操作的正确方法是什么？

Answer 1

fields.General_Information.Well = "name";应该在下面。您忘记实例化General_Information类型，因此它为null。此外，不确定将它们设置为partial类的需要。其实不应该。

fields.General_Information gi = new General_Information();
gi.Well = "name";
