Passing Array from C# to LABVIEW SharedDLL

[luky1374]

Hello,

I have written a LabVIEW SharedDLL with the following signature:

void CurveFitting(char Input[], DoubleArray ResultArray, DoubleArray1 OutputArray)

I'm trying to call this Function from C# but I guess I'm not using the right notation for passing an array from C# to LabVIEW. The first argument Input is a filename, the remaining two are arrays into which LabVIEW is to write the results.

This is the C# code to declare the DLL...

[DllImport("CFArray.dll")]
unsafe static extern void CurveFitting(string Input, out double dResultArray, out double dOutputArray);

... and this is how I'm calling it (unsuccessfully though)

private void btnCurveFit_Click(object sender, EventArgs e)
{           
            CurveFitting(txtFilePath.Text,  ResultArray, OutputArray);
}

Help is deeply appreciated! Thanks.
