无法将类型'System.Collections.Generic.List <string []>'隐式转换为'string []'

Question

下面是我的代码,它给出了一个错误: 无法将类型'System.Collections.Generic.List'隐式转换为'string []'

我试了好几次来解决这个错误.但我没有这样做.如果有任何身体可以建议什么可能是解决方案..谢谢:)

public GetContentResponse GetContent(abcServiceClient client, QueryPresentationElementIDsResponse querypresentationelementresponse)
        {
            GetContentRequest GetContentRequest = new GetContentRequest();
            GetContentResponse contentresponse = new GetContentResponse();
            querypresentationelementresponse = presentationElementId(client);
            List<string[]> chunks = new List<string[]>();
            for (int i = 0; i < querypresentationelementresponse.IDs.Length; i += 25)
            {
                chunks.Add(querypresentationelementresponse.IDs.Skip(i).Take(25).ToArray());
                contentresponse = client.GetContent(new GetContentRequest()
                {
                    IDs = chunks // here i get this error
                });
            }

            return contentresponse;
        }

您正在尝试将List分配给字符串数组.将列表转换为数组.由于您没有准确指出错误的位置,我想当您分配ID变量时.

以下代码将解决它:

public GetContentResponse GetContent(abcServiceClient client, QueryPresentationElementIDsResponse querypresentationelementresponse)
        {
            GetContentRequest GetContentRequest = new GetContentRequest();
            GetContentResponse contentresponse = new GetContentResponse();
            querypresentationelementresponse = presentationElementId(client);
            List<string> chunks = new List<string>();
            for (int i = 0; i < querypresentationelementresponse.IDs.Length; i += 25)
            {
                chunks.AddRange(querypresentationelementresponse.IDs.Skip(i).Take(25));
                contentresponse = client.GetContent(new GetContentRequest()
                {
                    IDs = chunks.ToArray()
                });
            }

            return contentresponse;
        }
