Question

Hi How do I retrieve the number from the following string,

{"number":100,"data":[test]}

The number could be of any length.

I used the following code. but it gives and error message

strValue.Substring((strValue.IndexOf(":")+1), (strValue.IndexOf("data")));

the output comes like

100,”data”:[

Thanks,

As noted by Jon, your input string seems to be a JSON string which needs to be deserialized. You can write your own deserializer, or use an existing library, such as Json.NET. Here is an example:

string json = @"[
  {
    ""Name"": ""Product 1"",
    ""ExpiryDate"": ""\/Date(978048000000)\/"",
    ""Price"": 99.95,
    ""Sizes"": null
  },
  {
    ""Name"": ""Product 2"",
    ""ExpiryDate"": ""\/Date(1248998400000)\/"",
    ""Price"": 12.50,
    ""Sizes"": null
  }
]";

List<Product> products = JsonConvert.DeserializeObject<List<Product>>(json);
