+## Cause
+
+A redundant length argument is passed to <xref:System.String.Substring%2A?displayProperty=nameWithType>, <xref:System.Span%601.Slice%2A?displayProperty=nameWithType>, <xref:System.ReadOnlySpan%601.Slice%2A?displayProperty=nameWithType>, or <xref:System.Memory%601.Slice%2A?displayProperty=nameWithType> when slicing to the end of a string or buffer.
+
+## Rule description
+
+An explicitly calculated length argument can be error-prone and is unnecessary when you're slicing to the end of a string or buffer.
+
+Code that omits the length argument is more readable and maintainable.
+
+## How to fix violations
+
+Remove the length argument.
+
+## Example
+
+The following code snippet shows a violation of CA1514:
+
+```csharp
+string message = "Hello World!";
+string world = message.Substring(6, message.Length - 6); // "World!"
+```
+
+```vb
+Dim message As String = "Hello World!"
+Dim world As String = message.Substring(6, message.Length - 6) ' "World!"
+```
+
+The following code snippet fixes the violation:
+
+```csharp
+string message = "Hello World!";
+string world = message.Substring(6); // "World!"
+```
+
+```vb
+Dim message As String = "Hello World!"
+Dim world As String = message.Substring(6) ' "World!"
+```
+
+## When to suppress warnings
+
+It's safe to suppress a violation of this rule if you're not concerned about the maintainability of your code.
+
+## Suppress a warning
+
+If you just want to suppress a single violation, add preprocessor directives to your source file to disable and then re-enable the rule.
+
+```csharp
+#pragma warning disable CA1514
+// The code that's violating the rule is on this line.
+#pragma warning restore CA1514
+```
+
+To disable the rule for a file, folder, or project, set its severity to `none` in the [configuration file](../configuration-files.md).
+
+```ini
+[*.{cs,vb}]
+dotnet_diagnostic.CA1514.severity = none
+```
+
