C# Signature:

[DllImport("kernel32.dll", CharSet=CharSet.Auto)]
static extern IntPtr lstrcpyn(
static extern IntPtr lstrcpy(
    [Out] StringBuilder lpString1,
    string lpString2,
    int iMaxLength);

User-Defined Types:

None.

    string lpString2);

Notes:

For those having trouble with StringBuilder, the below sample code uses the alternative IntPtr method.

Alternate definition (useful when dealing with buffer pointers):

[DllImport("kernel32.dll", CharSet=CharSet.Auto)]
static extern IntPtr lstrcpy(
    [Out] IntPtr lpString1,
    string lpString2);

VB.NET Signature:

<DllImport("kernel32.dll", CharSet:=CharSet.Auto)> _
Private Shared Function lstrcpy(<Out> lpString1 As StringBuilder, lpString2 As String) As IntPtr
End Function

Sample Code:

C#

[DllImport("kernel32", CharSet = CharSet.Auto)]
static extern IntPtr lstrcpyn(IntPtr dest, IntPtr src, int len);

void FillABuffer(IntPtr dest, int dest_maxlen, string source)
{
   IntPtr tmp_ptr = Marshal.StringToHGlobalAuto(source);
   lstrcpyn(dest, tmp_ptr, dest_maxlen);
   Marshal.FreeHGlobal(tmp_ptr);
}
