ContainsColumn Method

Overview

The ContainsColumn method returns a flag indicating whether the table schema contains a column with the specified name.

Column name matching behavior is case insensitive.

Declaration

/// <summary>
/// Gets flag indicating whether data table contains column with specified name
/// </summary>
/// <param name="columnName">Column name</param>
/// <returns>Flag indicating whether data table contains column with specified name</returns>
public bool ContainsColumn(string columnName)

Namespace and Assembly

Namespace: PocoDataSet.Data
Assembly: PocoDataSet.Data.dll

Behavior

• Delegates to _dataTableSchema.ContainsColumn(columnName).
• Returns true if the schema contains the column name; otherwise returns false.

Usage Example

using PocoDataSet.Data;
using PocoDataSet.IData;

DataTable table = new DataTable();
table.TableName = "Employee";
table.AddColumn("Id", DataTypeNames.INT32);
table.AddColumn("FirstName", DataTypeNames.STRING);

// Column name direct matching
bool hasId = table.ContainsColumn("Id"); // true

// Case insensitive column name matching
bool hasFirstName = table.ContainsColumn("firstname"); // true

// Column name not found even using direct match
bool hasName = table.ContainsColumn("Name"); // false
