The DimensionMismatchException type exposes the following members.

	Name	Description
	DimensionMismatchException	Constructs a new DimensionMismatchException.
	DimensionMismatchException(String)	Constructs a new DimensionMismatchException.
	DimensionMismatchException(SerializationInfo, StreamingContext)	Initializes a new instance of the MatrixNotPositiveDefiniteException class with serialized data.
	DimensionMismatchException(String, Exception)	Constructs a new DimensionMismatchException.
	DimensionMismatchException(DimensionType, String, DimensionType)	Constructs a new DimensionMismatchException.
	DimensionMismatchException(DimensionType, String, String)	Constructs a new DimensionMismatchException.
	DimensionMismatchException(DimensionType, String, DimensionType, String)	Constructs a new DimensionMismatchException.
	DimensionMismatchException(String, Exception, DimensionType, String, DimensionType, String)	Constructs a new DimensionMismatchException.

	Name	Description
	Data	Gets a collection of key/value pairs that provide additional user-defined information about the exception. (Inherited from Exception.)
	FirstDimensionType	Gets which dimension of the first object was mismatched.
	FirstParameterName	Gets the name of the first parameter whose dimensions were mismatched.
	HelpLink	Gets or sets a link to the help file associated with this exception. (Inherited from Exception.)
	HResult	Gets or sets HRESULT, a coded numerical value that is assigned to a specific exception. (Inherited from Exception.)
	InnerException	Gets the Exception instance that caused the current exception. (Inherited from Exception.)
	Message	Gets the error message and the parameter name, or only the error message if no parameter name is set. (Inherited from ArgumentException.)
	ParamName	Gets the name of the parameter that causes this exception. (Inherited from ArgumentException.)
	SecondDimensionType	Gets which dimension of the second object was mismatched.
	SecondParameterName	Gets the name of the second parameter whose dimensions were mismatched.
	Source	Gets or sets the name of the application or the object that causes the error. (Inherited from Exception.)
	StackTrace	Gets a string representation of the immediate frames on the call stack. (Inherited from Exception.)
	TargetSite	Gets the method that throws the current exception. (Inherited from Exception.)

	Name	Description
	Equals	Determines whether the specified Object is equal to the current Object. (Inherited from Object.)
	Finalize	Allows an object to try to free resources and perform other cleanup operations before it is reclaimed by garbage collection. (Inherited from Object.)
	GetBaseException	When overridden in a derived class, returns the Exception that is the root cause of one or more subsequent exceptions. (Inherited from Exception.)
	GetHashCode	Serves as a hash function for a particular type. (Inherited from Object.)
	GetObjectData	Populates a SerializationInfo with the data needed to serialize the target object. (Overrides ArgumentExceptionGetObjectData(SerializationInfo, StreamingContext).)
	GetType	Gets the runtime type of the current instance. (Inherited from Exception.)
	MemberwiseClone	Creates a shallow copy of the current Object. (Inherited from Object.)
	ToString	Creates and returns a string representation of the current exception. (Inherited from Exception.)

	Name	Description
	SerializeObjectState	Occurs when an exception is serialized to create an exception state object that contains serialized data about the exception. (Inherited from Exception.)

There are many reasons why a DimensionMismatchException may be thrown. In every case, the dimensions of some or all of the VectorT or MatrixT arguments involved in an operation are not compatible. Some examples of requirements that may be violated, resulting in a DimensionMismatchException, are:

• A method requires a MatrixT to be square. The matrix that was supplied is rectangular.
• An operation on two VectorT objects requires that the two vectors have the same length. Most operations on vectors have this requirement.
• A multiplication of a MatrixT and a VectorT requires that either the number of rows or the number of columns in the matrix equals the length of the vector.
• A multiplication of two matrices requires that the 'inner' dimensions are the same.

A number of properties give more information about the cause of the exception: FirstDimensionType, FirstParameterName, SecondDimensionType and SecondParameterName.

You can avoid this exception by verifying that the dimensions of the objects (RowCount, ColumnCount and/or Length) are compatible for the operation you want to perform.
