调用如下：

var folder = initFolder(Export_Folder.Text, "ExportMembers");

private string initFolder(string baseFolderPath, string folderName)
{
if (!baseFolderPath.EndsWith("\\")) baseFolderPath += "\\";
var folder = baseFolderPath + folderName;
if (!Directory.Exists(folder)) Directory.CreateDirectory(folder);
return folder;
}

HttpClient的异步Get/Post调用实例：

/// <summary>
/// Get请求模拟
/// </summary>
/// <param name="url">请求URL</param>
public void HttpRequest(string url)
{
HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
Task<HttpResponseMessage> response = client.GetAsync(url);
HttpResponseMessage result = response.Result;
this.queryResultPane.Text = result.Content.ReadAsStringAsync().Result;
}

Post调用如下：

var member = new
{
Code = "8fd8d3f6-4389-4315-a809-ce931dd427afm6",
Birthday = "2010-1-1",
Marital = "wei婚"
};

HttpClient client = new HttpClient();
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
//简单类型的参数,webApi方法里可以不定义参数,通过HttpContext.Current.Request.QueryString["Mobile"]来获取
Task<HttpResponseMessage> response =
client.PostAsJsonAsync(string.Format(U8688 + "MemberPoint/SaveMember"), member);
HttpResponseMessage result = response.Result;
this.Response.Output.Write(result.Content.ReadAsStringAsync().Result);
