Defines this spatial reference component from the specified ESRISpatialReference buffer.
[Visual Basic .NET] Public Sub ImportFromESRISpatialReference ( _ ByVal str As String, _ ByRef cBytesRead As Integer _ )
[C#] public void ImportFromESRISpatialReference ( string str, ref int cBytesRead );
[C++]
HRESULT ImportFromESRISpatialReference(
BSTR str,

);
[C++]
Parameters str str is a parameter of type BSTR cBytesRead [out] cBytesRead is a parameter of type long
Converts a string representation of a coordinate system into a spatial reference object. A sample string representation is below (reformatted for display).
