Create a class as below
By creating the list of class 'clsSalesTran' and a variable for 'Count'

创建如下类
通过创建类“clsSalesTran”的列表和“Count”的变量

Note: JsonProperty is mandatory from your Json String

注意：Json 字符串中的 JsonProperty 是必需的

public class SalesTransactions
{
     [JsonProperty("transactions")]
     public List<clsSalesTran> transactions {get;set;}
     public int count{get;set;}
}

Then you may use this class as below to deserialize

然后你可以使用这个类如下反序列化

SalesTransactions st = JsonConvert.DeserializeObject<SalesTransactions>(inputString)

Use the Deserialized object as below

使用反序列化对象如下

double paymentcharge = st.transactions[0].paymentcharge;
