好吧，我终于解决了我的问题。如果有更好的方法，请告诉我:-)
public DataSet getData(string strFoo)
{
string url = "foo";
HttpClient client = new HttpClient();
HttpResponseMessage response;
DataSet dsTable = new DataSet();
try
{
//Gets the headers that should be sent with each request
client.DefaultRequestHeaders.Accept.Add(new MediaTypeWithQualityHeaderValue("application/json"));
//Returned JSON
response = client.GetAsync(url).Result;
//converts JSON to string
string responseJSONContent = response.Content.ReadAsStringAsync().Result;
//deserializes string to list
var jsonList = DeSerializeJsonString(responseJSONContent);
//converts list to dataset. Bad name I know.
dsTable = Foo_ConnectAPI.ExtentsionHelpers.ToDataSet<RootObject>(jsonList);
//Returns the dataset
return dsTable;
}
catch (Exception ex)
{
System.Windows.Forms.MessageBox.Show(ex.Message);
return null;
}
}
//deserializes the string to a list. Utilizes JSON.net. RootObject is a class that contains the get and set for the JSON elements
public List<RootObject> DeSerializeJsonString(string jsonString)
{
//Initialized the List
List<RootObject> list = new List<RootObject>();
//json.net deserializes string
list = (List<RootObject>)JsonConvert.DeserializeObject<List<RootObject>>(jsonString);
return list;
}
RootObject包含将获取JSON值的获取集。
public class RootObject
{
//These string will be set to the elements within the JSON. Each one is directly mapped to the JSON elements.
//This only takes into account a JSON that doesn't contain nested arrays
public string EntityID { get; set; }
public string Address1 { get; set; }
public string Address2 { get; set; }
public string Address3 { get; set; }
}
创建上述类的最简单方法是使用json2charp，它将相应地对其进行格式化，并提供正确的数据类型。
以下是来自Stackoverflow的另一个答案，
它又没有考虑嵌套JSON。
internal static class ExtentsionHelpers
{
public static DataSet ToDataSet<T>(this List<RootObject> list)
{
try
{
Type elementType = typeof(RootObject);
DataSet ds = new DataSet();
DataTable t = new DataTable();
ds.Tables.Add(t);
try
{
//add a column to table for each public property on T
foreach (var propInfo in elementType.GetProperties())
{
try
{
Type ColType = Nullable.GetUnderlyingType(propInfo.PropertyType) ?? propInfo.PropertyType;
t.Columns.Add(propInfo.Name, ColType);
}
catch (Exception ex)
{
System.Windows.Forms.MessageBox.Show(ex.Message);
}
}
}
catch (Exception ex)
{
System.Windows.Forms.MessageBox.Show(ex.Message);
}
try
{
//go through each property on T and add each value to the table
foreach (RootObject item in list)
{
DataRow row = t.NewRow();
foreach (var propInfo in elementType.GetProperties())
{
row[propInfo.Name] = propInfo.GetValue(item, null) ?? DBNull.Value;
}
t.Rows.Add(row);
}
}
catch (Exception ex)
{
System.Windows.Forms.MessageBox.Show(ex.Message);
}
insert.insertCategories(t);
return ds.
}
catch (Exception ex)
{
System.Windows.Forms.MessageBox.Show(ex.Message);
return null;
}
}
};
然后最后将上述数据集插入到具有映射到JSON的列的表中，我利用了SQL批量复制和以下类
public class insert
{
public static string insertCategories(DataTable table)
{
SqlConnection objConnection = new SqlConnection();
//As specified in the App.config/web.config file
objConnection.ConnectionString = System.Configuration.ConfigurationManager.ConnectionStrings["foo"].ToString();
try
{
objConnection.Open();
var bulkCopy = new SqlBulkCopy(objConnection.ConnectionString);
bulkCopy.DestinationTableName = "dbo.foo";
bulkCopy.BulkCopyTimeout = 600;
bulkCopy.WriteToServer(table);
return "";
}
catch (Exception ex)
{
System.Windows.Forms.MessageBox.Show(ex.Message);
return "";
}
finally
{
objConnection.Close();
}
}
};
因此，上面的方法可以将来自webAPI的JSON插入数据库中。这是我要工作的东西。但是我绝对不希望它是完美的。如果您有任何改进，请相应地进行更新。
