i want to pass a string array from x++ to C# method. but it is giving an error : Argument '1' is incompatible with required type.

X++ code:

public static server str callfunction()

{

MagentoTrigger.MagentoAXServiceSoapClient soapClient; // .net webservice object

str ret;

str arry[2];

;

arry[1] = "101";

arry[2] = "102";

new InteropPermission(InteropKind::ClrInterop).assert();

soapClient = new MagentoTrigger.MagentoAXServiceSoapClient('MagentoAXServiceSoap');

ret = soapClient.Sync_Item_Selective(arry); // getting error : Argument '1' is incompatible with required type

//method : string Sync_Item_Selective(string[] array)

CodeAccessPermission::revertAssert();

return ret;

}

Sync_Item_Selective method takes "string array" as argument. but i am unable to pass string array from x++.

i have also tried with list, container. but i dont know how to use container in .net

plz suggest me, i just want to pass a string array to .net method.

Use a native .net array type by calling system class in your ax x++ code, build an array in native .net type and it should work.

Something like System.Array myArray ;

There is no magical conversion between X++ arrays and CLR arrays - you'll have to use the same type as the method expects. If it expects System.String[], your implementation should look like this:

System.String[] arry = new System.String[2](); arry.SetValue("101", 0); arry.SetValue("102", 1); (…) soapClient.Sync_Item_Selective(arry);

Just be sure that you look at the type of the service proxy, not the original .NET method. The types don't have to be the same.

@Martin,

I´m facing the same problem and the solution ( use of System.String[] str = new System.String[2]() ) is not working, I have tried a lot and keep throwing the same error described by vibhor.

@vibhor How u solved this issue?

Jefferson, if it complains about incompatible types, it means that your method expects something else then an array of strings. Please look at the type of the parameter and provide an argument of the same or compatible type.
