TextExtensionsToOfficeMathML Method
Returns a string containing the Office MathML (OMML) markup for the math text in the range.

Namespace: TextObjectModel
Assembly: ManagedTOM2 (in ManagedTOM2.dll) Version: 1.0.5577.41188
Syntax
Copy
public static string ToOfficeMathML(
	this TextRange range,
	[OptionalAttribute] OfficeMathMLMode mode,
	[OptionalAttribute] bool includeProperties
)

Parameters

range
Type: TextObjectModelTextRange
The range containing the math text.
mode (Optional)
Type: TextObjectModelOfficeMathMLMode
Determines how the markup is structured.
includeProperties (Optional)
Type: SystemBoolean
Whether to include document-level math properties.

Return Value

Type: String
A string containing one or more top-level OMML tags, depending on the math content and the value of mode and includeProperties.

Usage Note

In Visual Basic and C#, you can call this method as an instance method on any object of type TextRange. When you use instance method syntax to call this method, omit the first parameter. For more information, see Extension Methods (Visual Basic) or Extension Methods (C# Programming Guide).
Exceptions
ExceptionCondition
NotSupportedException The TOM implementation used by range does not support math.
Remarks

This method works by converting the Math RTF in the range to OMML, as the two representations are semantically identical.

Note: Setting the includeProperties parameter to true will result in an XML fragment (instead of a document). This will also occur if mode is set to Default or Inline and there are multiple math zones in the range.

Examples
The following example demonstrates how to build-up math text and then convert it to OMML:
C#
Copy
using (RichTextBoxEx rtb = new RichTextBoxEx()) {
    TextDocument doc = TextDocument.FromRichTextBox(rtb);

    TextRange range = doc.EntireRange;
    range.Text = "(a+b/c)/(u+x/y)";
    range.BuildUpMath();

    Console.WriteLine(range.ToOfficeMathML());
}
