Passing string array to webservice method

Question

I have a web service with this method:

[WebMethod]
public int[] stringTest(string[] tString)
{
 int numberOfStrings = tString.Length;
 int[] returnS = new int[numberOfStrings];
 for (int i = 0; i <= numberOfStrings; i++)
 { 
 returnS[i] = 1;
 }
 return returnS;
}

And then I'm trying to pass an array of strings to it from a client program as following:

var client = new WebServiceSample.WebService1SoapClient();
string[] parameterNames = { "Windsensor","Temperature sensor"};
test = client.stringTest(parameterNames);

But I'm getting these errors:

The best overloaded method match for 'SoapWebServiceClient.WebServiceSample.WebService1SoapClient.stringTest(SoapWebServiceClient.WebServiceSample.ArrayOfString)' has some invalid arguments

and

Argument 1: cannot convert from 'string[]' to 'SoapWebServiceClient.WebServiceSample.ArrayOfString'

What is wrong with my code?

• codingbiz: Can you include the complete error message?
• Gregor Primar: Refresh web service reference.
• L.B: Your error clearly says you should pass SoapWebServiceClient.WebServiceSample.ArrayOfString not string[]
• user1754598: Thanks for reply, how do i do that? how do connect SoapWebServiceClient.WebServiceSample.ArrayOfString to the array i defined parameterNames?

Answer 1

Try this

SoapWebServiceClient.WebServiceSample.ArrayOfString arrString = SoapWebServiceClient.WebServiceSample.ArrayOfString();
arrString.AddRange(parameterNames);

or

arrString.Add(....); //if that exists

A simple way is:

In JavaScript build a new array:

var myArray = new Array();
myArray.push([value1, value2,...]);

In C# just create an ICollection parameter to get your matrix:

[WebMethod(EnableSession = true)]
public MyMethod[] GetMatrixFromJavascript(System.Collections.ICollection myArray)
{ 
 ... 
}
