Assembly: Extreme.Numerics (in Extreme.Numerics.dll) Version: 8.1.23
Overload List
| Read | Reads a quadratic programming model from a stream. |
| Read | Reads a quadratic programming model from an MPS file. |
MpsReader.ReadQuadraticProgram(StreamReader)
public static QuadraticProgram ReadQuadraticProgram(
StreamReader reader
)Parameters
- reader StreamReader
- A StreamReader.
Return Value
QuadraticProgramThe LinearProgram read in MPS format from reader.
Remarks
Use this method to read a quadratic program from a stream in MPS format.
Several extensions of the MPS format have been defined over the years. The current implementation of MpsReader doesn't support these extensions. A FormatException is thrown when an unrecognized extension is found.
The MPS format is also used to specify Integer Programming (IP) and Mixed Integer Programming (MIP) problems. The LinearProgram class does not support these types of problems. When integer variables are encountered in an MPS file, a NotSupportedException is thrown.
Exceptions
| Argument | reader is null. |
| Format | The data is not in correct MPS format. |
| Not | The data contains features, such as integer variables, that are not supported. |
| IOException | An I/O error has occurred. |
MpsReader.ReadQuadraticProgram(String)
public static QuadraticProgram ReadQuadraticProgram(
string path
)Parameters
- path String
- The path to the MPS file.
Return Value
QuadraticProgramThe QuadraticProgram contained in the file specified by path.
Remarks
Use this method to read a quadratic program from a file in MPS format.

| Format | The data is not in correct MPS format. |
| Not | The data contains features, such as integer variables, that are not supported. |
| IOException | An I/O error has occurred. |
| Unauthorized | The caller does not have the required permission. |
| Argument | path is a zero-length string, contains only white space, or contains one or more invalid characters as defined by GetInvalidPathChars(). |
| Argument | path is null. |
| Path | The specified path, file name, or both exceed the system-defined maximum length. For example, on Windows-based platforms, paths must be less than 248 characters, and file names must be less than 260 characters. |
| Directory | The specified path is invalid, (for example, it is on an unmapped drive). |
| File | The file specified in path was not found. |
| Argument | path is null. |
