Humanizer.TruncateExtensions

TruncateExtensions Class​

Allow strings to be truncated

public static class TruncateExtensions

Inheritance System.Object → TruncateExtensions

Methods​

TruncateExtensions.Truncate(this string, int) Method​

Truncates a string to a specified maximum length using the default truncation string ("…") and fixed-length truncator.

public static string? Truncate(this string? input, int length);

Parameters​

input System.String

The string to be truncated. Can be null.

length System.Int32

The maximum length of the result string, including the truncation indicator.

Returns​

System.String
The truncated string if its length exceeds length, otherwise the original string. Returns null if input is null.

Example​

"This is a long string".Truncate(10) => "This is a…"
"Short".Truncate(10) => "Short"
null.Truncate(10) => null

Remarks​

The default truncation indicator is "…" (ellipsis), and truncation occurs from the right side of the string.

TruncateExtensions.Truncate(this string, int, ITruncator, TruncateFrom) Method​

Truncates a string to a specified maximum length using a custom truncator and truncation direction.

public static string? Truncate(this string? input, int length, Humanizer.ITruncator truncator, Humanizer.TruncateFrom from=Humanizer.TruncateFrom.Right);

Parameters​

input System.String

The string to be truncated. Can be null.

length System.Int32

The maximum length of the result string, including the truncation indicator.

truncator ITruncator

The ITruncator implementation to use for truncation logic. Must not be null.

from TruncateFrom

Specifies from which side of the string to truncate. Default is Right.

Returns​

System.String
The truncated string if its length exceeds length, otherwise the original string. Returns null if input is null.

Exceptions​

System.ArgumentNullException
Thrown when truncator is null.

Example​

"This is a long string".Truncate(10, Truncator.FixedLength, TruncateFrom.Left) => "…ng string"
"This is a long string".Truncate(10, Truncator.FixedNumberOfWords) => "This is…"

TruncateExtensions.Truncate(this string, int, string, ITruncator, TruncateFrom) Method​

Truncates a string to a specified maximum length using a custom truncation string, truncator, and direction.

public static string? Truncate(this string? input, int length, string? truncationString, Humanizer.ITruncator truncator, Humanizer.TruncateFrom from=Humanizer.TruncateFrom.Right);

Parameters​

input System.String

The string to be truncated. Can be null.

length System.Int32

The maximum length of the result string, including the truncation indicator.

truncationString System.String

The string to use as the truncation indicator (e.g., "...", "…", or any custom string). Can be null or empty.

truncator ITruncator

The ITruncator implementation to use for truncation logic. Must not be null.

from TruncateFrom

Specifies from which side of the string to truncate. Default is Right.

Returns​

System.String
The truncated string if its length exceeds length, otherwise the original string. Returns null if input is null.

Exceptions​

System.ArgumentNullException
Thrown when truncator is null.

Example​

"This is a long string".Truncate(10, "...", Truncator.FixedLength, TruncateFrom.Right) => "This is..."
"This is a long string".Truncate(10, "…", Truncator.FixedNumberOfWords, TruncateFrom.Left) => "… string"

Remarks​

This is the most flexible truncation method, allowing full customization of the truncation behavior.

TruncateExtensions.Truncate(this string, int, string, TruncateFrom) Method​

Truncates a string to a specified maximum length using a custom truncation string and fixed-length truncator.

public static string? Truncate(this string? input, int length, string? truncationString, Humanizer.TruncateFrom from=Humanizer.TruncateFrom.Right);

Parameters​

input System.String

The string to be truncated. Can be null.

length System.Int32

The maximum length of the result string, including the truncation indicator.

truncationString System.String

The string to use as the truncation indicator (e.g., "...", "…", or any custom string). Can be null or empty.

from TruncateFrom

Specifies from which side of the string to truncate. Default is Right.

Returns​

System.String
The truncated string if its length exceeds length, otherwise the original string. Returns null if input is null.

Example​

"This is a long string".Truncate(10, "...") => "This is..."
"This is a long string".Truncate(15, "--") => "This is a lo--"
"This is a long string".Truncate(10, "...", TruncateFrom.Left) => "...string"
