Properties

ColumnName

This property returns the name of the column.

public string ColumnName { get; set; }

Property Value

string

Remarks

None

MaxLength

This property returns the maximum length of the column.

public int MaxLength { get; set; }

Property Value

int

Remarks

The maximum length is user defined and not in any way enforced in our default FeatureSource implementation. It is mainly for display purposes or when dealing with a known Feature Source type.

TypeName

This property returns the type name of the column.

public string TypeName { get; set; }

Property Value

string

Remarks

This property is freeform and the type name is not tied to anything. It is wise to try and use familiar type names such as string, integer, date, etc., although it may not fit every different type of FeatureSource. We suggest thar you avoid using this property unless you know the types beforehand or simply want them for display purposes.
